3. A person of mass 100 kg stands on a scale in an elevator. The elevator moves downward at a steady speed. Is the scale reading greater than, less than, or equal to 1000 N? Justify your answer.
Answer:
less than
Explanation:
Given;
mass of the person, m = 100 kg
acceleration due to gravity, g = 9.8 m/s²
The reading on the scale is determined by applying Newton's second law of motion;
R = mg - ma
R = m(g-a)
at constant velocity, the acceleration is zero
a = 0
R = m(g-0)
R = mg
R = 100 x 9.8
R = 980 N
Thus, the scale reading is equal to the weight of the person but less than 1000 N

A person driving a car suddenly applies the brakes. The car takes 7.0 s to come to rest while traveling 26 m at constant acceleration. What was the initial speed of the car (in m/s)?
Answer:
7.43 m/s
Explanation:
Time taken for car to stop = 7.0 s
distance traveled before coming to rest = 26 m
Final speed of the car = 0 m/s (since it stops)
initial speed of the car = ?
To get the final speed, we use the equation
s = [tex]\frac{1}{2}t(u + v)[/tex]
where
s is the distance traveled before stopping
u is the initial speed = ?
v is the final speed = 0 m/s
t is the time = 7 s
substituting values, we have
26 = [tex]\frac{1}{2}*7*(u + 0)[/tex]
26 = 3.5u
u = 26/3.5 = 7.43 m/s
a current of 5 ampere is passed for 2 hours in an electric iron having a resistance of 100 ohms calculate the heat produced
Answer:
[tex] \boxed{\sf Heat \ produced \ (H) = 5 \ kWh} [/tex]
Given:
Resistance (R) = 100 Ω
Current (I) = 5 A
Time (t) = 2 hours
To Find:
Heat developed (H) in the electric iron
Explanation:
Formula:
[tex] \boxed{ \bold{ \sf H = I^2Rt}}[/tex]
Substituting values of I, R & t in the equation:
[tex] \sf \implies H = {5}^{2} \times 100 \times 2 \\ \\ \sf \implies H = 25 \times 100 \times 2 \\ \\ \sf \implies H = 5000 \\ \\ \sf \implies H = 5 \: kWh [/tex]
[tex] \therefore[/tex]
Heat developed (H) in the electric iron = 15 kWh
List two examples of the following states of matter: solids, liquids, and gases. Please answer in NO LESS THAN 3 complete sentences.
Answer:
Matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around. Liquid matter is made of more loosely packed particles.
Key Takeaways: Examples of Solids, Liquids, and Gases
A solid has a defined shape and volume. A common example is ice. A liquid has a defined volume, but can change state. An example is liquid water.There are four natural states of matter: Solids, liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates. In a solid, particles are packed tightly together so they don't move much.

a cross country runner runs 10 km in 40 minutes. what is his average speed
◈ Average speed is measured as the ratio of total distance travelled to the total time taken.
Given : d = 10km and t = 40min
To Find : Vav
_________________________________
፨ Conversion :-
60 min = 1 h
40 min = 40/60 = 2/3 h
[tex]:\implies\sf\:V_{av}=\dfrac{d}{t}[/tex]
[tex]:\implies\sf\:V_{av}=\dfrac{10\times 3}{2}[/tex]
[tex]:\implies\sf\:V_{av}=\dfrac{30}{2}[/tex]
[tex]:\implies\:\boxed{\bf{\orange{V_{av}\:15\:kmph}}}[/tex]

5. What is the velocity of a Nolan Catholic football player if he runs 200.0 m in 24.0 s?
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed {\sf{8.33 \: m \:/s \: }}}}} [/tex]
Explanation:
Distance travelled = 200 metre
Time taken = 24 second
Velocity = ?
Finding the velocity
[tex] \boxed{ \sf{velocity = \frac{distance \: travelled \: }{time \: taken}}} [/tex]
[tex] \dashrightarrow{ \sf{velocity = \frac{200 \: m}{24 \: s} }}[/tex]
[tex] \dashrightarrow{ \sf{velocity = 8.33 \: m/s}}[/tex]

write down formula of power
Answer:
Power is a measure of the amount of work that can be done in a given amount of time. So, the formula is the energy or work divided by time:
P = W ÷ T, where p is power , w is work and t is time.
2. What is the difference between distance and displacement?
Answer:
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
Explanation:
:)
Answer: The complete length of the path between any two points is called distance. Displacement is the direct length between any two points when measured along the minimum path between them.
