why is the unit of temperature is called derived unit
Explanation:
The SI unit of power is the kilogram-meter2 per second cubed, which is called the watt (1 W = 1 kg-m2/s3). Since power is the energy used per unit of time, it is derived as the energy/time quotient.
Kelvin is a fundamental unit! It's a lot easier to measure temperature than to measure the motion of component particles. Hence, we can accept it as a fundamental quantity. Time is said to be a fundamental unit because it is not dependent on one or more units

Robin jogs with an average speed of 5.5 m/s for 3.3s.
What was her distance travelled in meters?
Answer:
18.15m
Explanation:
Speed * Time = Distance
5.5 * 3.3 = 18.15m
The distance traveled by Robin is equal to 18.15 m with an average speed of 5.5 m/s for 3.3s.
What is the average speed?The average speed can be explained as the total distance covered by the object in a definite time. The average speed can be considered a scalar quantity as it exhibits magnitude and no direction.
The average speed of a physical system can be determined from the ratio of the total distance traveled by the system to the time taken to cover that distance.
The average speed equation of a physical system can be written as follows:
Average speed = Total distance/total time taken
Given, the average speed of the Roin, = 5.5 m/s
The time is taken by Robin for jogging = 3.3 s
The average speed of the Robin can be determined as:
Average spped = Distance/ time
5.5 = Distance/3.3
Distance traveled by Robin = 5.5 × 3.3 = 18.15 m

A farmer wants to determine which of two brands of cow feed is best for the cows on a farm. Before using one of the feeds on all the cows, the farmer decides to conduct an experiment using 36 individual cows. Which of the two plans for randomly assigning the treatments should the farmer use? Explain. (4 points) Plan A: Choose the 18 cows that are lowest in weight. Feed Brand K to all 18 of those cows. Feed Brand L to the remaining 18 cows. Plan B: Choose 18 of the 36 cows at random. Feed Brand K to those 18 cows and Brand L to the remaining 18 cows. Plan B, because the sample of cows is randomly chosen Plan A, because the cows that are lowest in weight need the feed the most and should be treated first Plans A and B are equivalent because they both follow experimental design. Plans A and B are both poorly designed because there are not enough cows to test. The plans cannot be evaluated from the information given.
Answer:
Plan B, because the sample of cows is randomly chosen
A dog walks 8.0 meters due north and then 6.0 meters due east. Determine the magnitude of the dog's total displacement to the nearest tenths
Answer:
the magnitude of the dog's total displacement to the nearest tenths = 53.12°
Explanation:
Given that:
a dog walks 8.0m due to the north and 6.0 m due east.
We can determine the magnitude of the dog's total displacement by using the Pythagoras theorem.
Consider the north direction be the opposite and the east direction to be the adjacent, therefore the hypotenuse will be the dog's total displacement.
So, suppose hypotenuse is represented by a
the opposite represented by b, and the adjacent represented by c
Then;
a² = b² + c²
a² = 8² + 6²
a² = 64 + 46
a² = 100
a =[tex]\sqrt{100[/tex]
a = 10.0 m
However, the magnitude of the dog's total displacement is calculated by taking the tangent of the system.
tan θ = opposite / adjacent
tan θ = b/c
tan θ = 8/6
tan θ = 4/3
tan θ = 1.333
θ = tan⁻¹ (1.333)
θ = 53.12
the magnitude of the dog's total displacement to the nearest tenths = 53.12°

If a questions says "at what point does the ball stop?" what is it asking for?
Explanation:
If a question says "at what point does the ball stop?", it means we need to find the position of the ball when its final velocity is equal to 0. It can be calculated using the equation of kinematics as follows :
d = ut + (1/2) at²
and
v²-u²=2ad
Where, u is initial velocity, v is final velocity, a is acceleration, t is time and d is displacement.
What is the volume of 27 g of aluminium?
Answer:10cm3
Explanation:Volume Al = (27g Al)/(2.70g/cm3 Al) = 10cm3 Al. So, 27g of Al has a volume of 10cm3. *
Answer:
Explanation:
as we know that
density=mass/volume
given mass of Al=27 g
density of Al=2.70g/cm^3
volume =mass/density
volume=27/2.70
volume=10 cm³
so 27 g of Al has volume of 10 cm³
Explain any two areas affected by migration
Answer:
Migration is affected by various factors like age, sex, marital status, education, occupation, employment etc. Age and sex are main demographic factors that affect the migration. Men, generally, migrate to other places quite often though there are more women who migrate to husbands' places after marriage.Answer:
Social aspect:
In the place of origin migration can create a lack of food, accomodation and other basic services and facilities. Because of influence of lanuage, tradition , culture etc carried by immigrants the native language culture and tradition of the target place may get endangered. This may create diverseness of culture language so there can be disunity and factionalism in society. Target place may have to experience unemployment and criminal activities may take a lead.The place of origin may have to suffer from depopulation and slow development as well..
Economic aspect:
Target place may get some more manpower which results in fast development. But if the manpower is enough or more then unemployment can be resulted. This may cause brain drain. Poverty may take a lead. Landlords may exploit labourers ....
If the distance between two charged particles is doubled, the force between them changes by a factor of ___. (1 point)
1/2
1/4
2
4
Answer:
decreases 1/4 of the original value
If the distance between two charged particles is doubled, the force between them changes by a factor of 1/4.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Force between two charge particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
If the distance between two charged particles is doubled, the force between them changes by a factor of 1/4.

Need help! Photo says all! Will mark brainliest :)
Answer:
C-D
Explanation:
As you can see from the graph, the distance from A to B was from 0 m to 6 m in a duration of 3 seconds.
Divide 6 meters by 3 seconds to find the speed:
6 ÷ 3 = 2 m/s
B-C is not moving due to a straight line as said in the graph, so speed is
0 m/s.
There is also C-D since the car traveled from a distance of 9 meters
(6 -(-3) = 9) in 3 seconds too. (NOTE: The graph line going down does not mean it is slowing down, but rather going to a certain distance like going backwards)
Divide 9 meters by 3 seconds to get the speed:
9 ÷ 3 = 3 m/s
Between A-B, B-C, and C-D, C-D has the fastest speed recorded with 3 m/s.
A-D does not count here as the line has no connection between point A and point D.

Which represent correct variations of the formula for speed? Check all that apply. t = d/s s = d/t t = s/d s = dt d = st d = s/t
Answer: 1 2 5
Explanation:
Galileo Galilei, an Italian physicist, is credited with being the first to calculate speed by dividing it by the distance traveled and the time required. Galileo defined speed as the distance covered in a predetermined period of time. Thus option A, B. E is correct.
What represent correct variations of the formula for speed?Speed is determined by dividing the distance by the time. Calculating the units for speed requires knowledge of the units for both time and distance. Since the distance is measured in meters (m) and the time is measured in seconds, the units in this example will be meters per second (m/s) (s).
That is speed = distance time. Alternatively, you can calculate the time by dividing the distance traveled by the speed. You can figure out the third input if you know two of the inputs.
Therefore, For instance, if a car drives 120 miles (ca. 193 km) in 2 hours, we may calculate the speed as 120 × 2 = 60 miles per hour (ca. 97 km/h).

Si la aceleración de gravedad en la superficie del planeta Mercurio es de 3,7 m/s2, entonces ¿cuál sería el peso de una persona de 60 kg de masa que se encuentre sobre su superficie?
Answer:
W = 222 N.
Explanation:
The qiestion says" If the acceleration of gravity on the surface of the planet Mercury is 3.7 m / s2, then what would be the weight of a person with mass 60 kg on its surface? "
Mass of the person, m = 60 kg
The acceleration due to gravity on the surface of gravity is 3.7 m/s²
We need to find the weight of a person on the surface of Mercury.
Weight of an object is given by :
W = mg
So,
W = 60 kg × 3.7 m/s²
W = 222 N
Hence, the person will weigh 2222 N on the surface of Moon.

A bus travels 210 km south along a straight
path with an average velocity of 85 km/h to
the south. The bus stops for 25 min, then it
travels 230 km south with an average velocity
of 73 km/h to the south.
How long does the total trip last?
Answer in units of h.
Answer:
6.04 hr
Explanation:
The bus first travels a distance of 210 km south at an average velocity of 85 km/h. The time, t it takes to cover this distance is gotten from d = vt and t = d/v where d = distance and v = velocity.
So, t = 210 km/85 km/h = 2.47 h
The bus then stops for 25 min. We convert 25 min to hours by dividing by 60.
So 25 min = 25/60 hr = 5/12 h = 0.42 h
The bus then travels 230 km south at an average velocity of 73 km/h.
The time it takes to cover this distance is t = 230 km/73 km/h = 3.15 h
So, the total time for the trip is the sum of each individual time, which is 2.47 h + 0.42 h + 3.15 h = 6.04 hr
So, it takes 6.04 hr for the total trip
