Amy weighs 35 kg and her dad weighs 85 kg. They are roller skating. Amy challenges her dad to race. They stand poised at the starting line. Her dad yells, “Go!” Who will go faster and why?
Answer:
Amy because she was less than her dad and due to the dads weight being more it'll add friction to the skates which will slow him down.
Explanation:
Answer:
Amy will win because she ways less than her dad.

How do you think the weather and climate might change in the area around Mt. Everest?
Answer:
It does change if the weather is bad then very soon the climate will turn bad when the climate is unfavourable then the sourrounding will be affected. For example if the area around the Mt. Everest is Hot & Humind the ice would start melting & it would lead to way more issues.

examples of positive effects of fluid forces
Answer:
fluid dynamic forcesln physics fluid mechanicsPLEASE. A 20 kg box is being pulled across a floor by a horizontal rope. The tension in the rope is 99 Newtons. The coefficient of friction is 0.25. What is the force of friction on the box? What is the acceleration of the box?
Answer:
Force of Friction = -50 (N)
Acceleration = 2.45 (m/s^2)
Explanation:
Force of Friction = f = N * coefficient of friction
N = m * g
=> Force of Friction = m * g * coefficient of friction
f = 20 * 10 * -0.25 = -50 (N)
------------------------------------------------------
(1) F net = F + f
(2) F = m * a
(1) F net = 99 - 50 = 49
(2) a = 49 / 20 = 2.45 (m/s^2)

The sleigh is being pulled with a force of 800N and has a mass of 200 Kg.
What is the acceleration in m/s/s?
Answer:
a = 4m/s²
Explanation:
Given:
F = 800N
m = 200 kg
Unknown:
acceleration or a
Formula and solution:
a = F/m
a = 800 kg.m/s² ÷ 200 kg
Final Answer:
a = 4 m/s²
in the solution there's a two same unit and that is kg so the same unit will be cancelled and the rest is going to aapply in the answer that is 4 so if combine it the final answer is 4 m/s²

Which factor can decrease the kinetic energy of an object? (3 points)
Increase in speed
Decrease in speed
Increase in temperature
Decrease in volume
Answer:
Decrease in speed
Explanation:
Increasing an object's velocity can decrease kinetic energy. *The velocity of an object has no effect on kinetic energy. *Increasing an object's velocity can increase kinetic energy. Increasing an object's velocity can increase kinetic energy.

Which is a valid velocity reading for an object?
A.45 m/s
B. 45 m/s north
C. 0 m/s south
D. 0 m/s
The valid option would be 45 m/s north. This option specifies a velocity of 45 meters per second in the north direction. It includes both the magnitude (45 m/s) and the direction (north) of the velocity. Hence the correct option is (A).
A. 45 m/s: This indicates a velocity of 45 meters per second without specifying the direction. It represents the magnitude of the velocity but does not indicate a particular direction.
B. 45 m/s north: This indicates a velocity of 45 meters per second in the north direction. It specifies both the magnitude (45 m/s) and the direction (north).
C. 0 m/s south: This indicates a velocity of 0 meters per second in the south direction. No velocity. It specifies both the magnitude (0 m/s) and the direction (south).
D. 0 m/s: This indicates a velocity of 0 meters per second, meaning the object is not moving. It represents zero speed and zero direction.
The correct option is (A).

If you put food coloring in room temperature water, the coloring spreads throughout the water.
The water causes the color to spread mainly because:
•the food coloring is heavy
•food coloring molecules are small
•the water is warm
•the water molecules are in motion
Answer: Water molecules are in motion
Claim 2: Firing the thrusters only slowed the pod, it didn’t stop; the pod hit the space station, which made it bounce and move in the opposite direction. This would happen if.
The force exerted by the thrusters caused the pod to change direction. It depends on the direction and the strength of the force exerted.
