Answer: A-B-C-E-G-K-H-I
Explanation:
Ok, we start at A.
16 pints = x gallons.
We know that:
1 pint = 0.125 al
then:
16pint = 16*(0.125gal) = 2 gal.
The second letter is B.
Now we have:
12,320 yd = X mi
And we know that:
1 mi = 1760 yd.
Then 12,320yd = (12,320/1760) mi = 7mi
the letter is C.
Now we have:
432 cups = X gals
and:
1 cup = 0.0625 gal
then 432 cups = 432*(0.0625 gal) = 27 gal.
The next letter is E.
Now we have:
1/4 ton = X pounds.
And 1 ton = 2000 pounds
then 1/4 ton = (1/4)*2000 pounds = 500 pounds
The next letter is G.
Now we have:
3.5 gal = X ounces.
and we know that:
1 gal = 128 oz
Then:
3.5 gal = 3.5*(128oz) = 448oz
The next letter is K.
Now we have:
1/2 day = x minutes.
and we know that:
1 day = 24*60 min = 1440 min
then 1/2 day = (1/2)*1440 min = 720 min.
The next letter is H.
Now we have:
360 in = x yd
And we know that:
1yd = 36 inches.
then 360 in = (360/36) = 10 yd.
The next letter is I
Now we have:
56 cups = x quarts.
and we know that;
1cup = 0.25 quart
then: 56 cups = 56*0.25 quart = 14
So here this ends.
Then the code is:
A-B-C-E-G-K-H-I

2. How long will it take for a ball thrown vertically upward with an initial velocity of
480 km/h to reach its maximum height?
Answers
Answer:
13.33 seconds
Explanation:
At maximum height, the equation of motion becomes:
v = u + at
Since the object was thrown vertically, the initial velocity (u) is zero and the acceleration (a) becomes the acceleration due to gravity (10 m/s2). The equation becomes:
v = at
v = 480 km/hr = 133.333 m/s
10t = 133.333
t = 133.333/10
t = 13.33 seconds.
The time for the ball thrown vertically with a velocity of 480 km/hr to reach the maximum height is 13.33 seconds.
Your friend's car is stuck in the snow. You push very hard and become very 1 tired but the car won't move. Did you do work?
Yes, work was done
No, work wasn't done
Answers
Answer:
Yes you worked
Explanation:
You may have not seen a good outcome but you did put effort in.
When a force is applied on the car and it doesn't move then it simply means
work wasn't done.
The formula for work is given below:
Work = Force ₓ Displacement
For work to have been done , the applied force must cause the object to
change its position(displacement).
In situations where the force applied doesn't cause a change in position then work can't be calculated. This means no work was done on the car despite the applied force causing him to be tired.

Titus drives his jetski a distance of 1000 meters in 7.045 seconds. How fast was he moving in meters per second? How fast was he moving in miles per hour?
Answers
Answer:
a) v = 141.9 m/s
b) v = 317.4 miles/h
Explanation:
a) How fast was he moving in meters per second?
[tex] v = \frac{d}{t} = \frac{1000 m}{7.045 s} = 141.9 m/s [/tex]
Hence, the jet ski is moving at 141.9 meters per second.
b) How fast was he moving in miles per hour?
[tex] v = \frac{d}{t} = \frac{1000 m}{7.045 s} = 141.9 m/s*\frac{3600 s}{1 h}*\frac{1 mile}{1609.34 m} = 317.4 miles/h [/tex]
Therefore, the jet ski is moving at 317.4 miles per hour.

Which statement describes a characteristic of most metals?
A.They can be formed into wires.
B.They cannot be shaped by hammering or pounding
C.They are liquid at room temperature
D.They are poor conductors.
Answers
Answer:
Answer is A
Explanation:
A on edge
Answer:
A. They can be formed into wires
Explanation:
Metals are also malleable, which means that they can be hammered into very thin sheets without breaking. They are ductile, which means that they can be drawn into wires. When a fresh surface of any metal is exposed, it will be very shiny because it reflects light well. So they can be shaped by hammering or pounding. Metals are not liquids except mercury but most metals are not liquid at room temperature. Metals are actually great conductors/conductibility, which means they have a heat factor in them which most metals do.
Therefore, this shows that A. They can be formed into wires. Is the best choice
Hope this helped :D

The electrostatic force that a charged particle, q1q1 , exerts on another charged particle, QQ , at a distance r1r1 , is FF . A second charged particle, q2q2 , exerts the same force FF on QQ at half the distance r1r1 . What is the value of q1q1 in relation to q2q2 ?
Answers
Answer:
q₁ / q₂ = 4
Explanation:
In this exercise we must use Coulomb's law
F = k q₁q₂ / r²
For this case the electric force is
F = k q₁ Q / r₁²
indicate that another particle q₂ has the same force on Q, but for r₂ = r₁ /2
F = k q₂ Q / r₂²
we equate the two equations
q₁Q / r₁² = q₂ Q / r₂²
we substitute r₂
q₁Q / r₁² = q₂ Q / (r₁/2)²
q₁ = q₂ 4
the relationship between the two charges is
q₁ / q₂ = 4

Melissa and Rory live near a bike trail, 21 km apart. They plan to meet at a park mid-way between their homes. They start from their homes at the same moment, and ride toward each other. Both ride at 7 km/hour. Melissa’s dog Jessie knows this routine. He starts with Melissa, and runs at 18 km/hour toward Rory. When he reaches Rory, he turns around and runs toward Melissa. He reaches Melissa, turns around and runs toward Rory again, and so on, until Melissa and Rory meet. How many kilometers did Jessie run?
Answers
Answer:
27km.
Explanation:
Jessie will run for a duration of time, which is the time it takes for Melissa and Rory to meet each other.
Together combined, Melissa and Rory runs at 14km/h. The bike trail is 21km, so it will take 1.5 hours.
Jessie runs at 18km/h, so Jessie will run 18 * 1.5 = 27km.

NEED HELP ASAP Carlos is analyzing the results of a recent scientific study about gravity. Scientists recorded that the experimental value of gravity was 10.24 m/s² and the general accepted value of gravity is 9.81 m/s². Calculate the percent error of the experimental versus accepted values of gravity. 5.01% 4.38% 2.66% 9.27%
Answers
Answer:
4.38 %
Explanation:
Given that,
The experimental value of gravity is 10.24 m/s²
The general accepted value of gravity is 9.81 m/s²
We need to find the percent error of the experimental versus accepted values of gravity.
The formula used to find the percentage error is given by :
[tex]\%=\dfrac{|\text{original value-calculated value}|}{\text{original value}}[/tex]
Putting all the values:
[tex]\%g=\dfrac{|9.81-10.24|}{9.81}\times 100\\\\\%g=4.38 \%[/tex]
So, the percentage error is 4.38 %.
A satellite’s original velocity is 10,000 m/s. After 60 seconds it s going 5,000 m/s. What is the acceleration? Remember acceleration = (final speed – initial speed) ÷ time .
(p.s i think this is physics? i don't know i just know its science so if anyone can help with this it would be greatly appreciated)
Answers
Explanation:
Given that,
Orginal speed, u = 10,000 m/s
Final speed, v = 5,000 m/s
Time, t = 60 s
To find,
Acceleration of the satellite.
The acceleration of an object is equal to the change in its speed divided by time. So,
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{5000-10000}{60}\\\\a=-83.34\ m/s^2[/tex]
So, the acceleration of the satellite is [tex]83.34\ m/s^2[/tex] and it is deaccelerating.

Answers
A child slides down a hill on a toboggan with acceleration of 1.8 m/s2. if she starts from rest, how far has she traveled in: 2 seconds
Answer:
2.4 m
Explanation:
From the question above,
Applying equation of motion,
s = ut+at²/2....................... Equation 1
Where t = time, u = initial velocity, a = acceleration, s = distance.
make s the subject of the equation,
Given: a = 1.8 m/s², t = 2 seconds, u = 0 m/s (from rest)
Substitute these value into equation 1
s = 0(2)+1.8(2²)/2
s = 1.2(4)/2
s = 2.4 m.
Hence she has traveled 2.4 m

Question 8
Four materials are put into small containers. These materials
are then moved from the small containers into larger
containers. Which material will spread out to completely fill
a larger container?
O air
oice
O sand
water
Answers
Answer:
Air
Explanation:
Matter exists in three states namely; solid, liquid and gas. These three states contain molecules/particles that behave differently from one another. The particles of gas are scattered in such a way that they move randomly in a fast motion. This causes the ability of gas particles to diffuse in an open space i.e. spread quickly
In the options of materials given in this question, AIR represents a gaseous substance, hence, it is made up of particles that move rapidly in a random manner. This will cause it to spread out (diffuse) to completely fill a larger container it is placed in.

Answers
Answer:
The object moves 6 m in every second.
Explanation:
When we say something is constant, we simply means that it does not change with time i.e it the same through out irrespective of time.
Now, let us answer the question given above.
An object moving at a constant speed of 6 m/s. Has the following characteristics:
1. The object moves 6 m in every second.
2. The object is not accelerating since it has a constant speed. Therefore, the acceleration of the object is zero.
3. The object is moving as it covers a distance of 6 m in every second.
4. The speed remains the same since the speed of object is constant.
Thus, the right answer to question is: The object moves 6 m in every second.
