Answer:
mv-mu
Explanation:
momentum is the mass by velocity of an object. change in momentum means there was an initial momentum and a final momentum. V represents the final momentum and U represents the initial momentum. So minus the momentum values. (Final momentum (mv) minis initial momentum (mu)
<span>Well the Wheels would help to move the box but you need to have in mind that if the box is heavy you must make sure that it does not role-down because of how heavy the box is</span>
Answer:
600 m is required for smaller plane to reach its takeoff speed.
Explanation:
We have equation of motion
80 = 0 + a x 30
a = 2.67 m/s²
Now finding distance traveled by second flight
v² = u²+2as
40² = 0²+2 x 2.67 x s
s = 300 m
So 300 m is required for smaller plane to reach its takeoff speed.
Answer:
The final stored energy will become half.
Explanation:
We know that stored energy in the capacitor is given as
C=capacitance
V=Voltage difference
E=Energy
d=Distance between plates
A=Area
If the distance between plates get double ,say d' = 2 d
Then stored energy
Therefore the final stored energy will become half.
Your question: What happens to particles in a surface wave (such as a water wave)?
My answer: B, They move perpendicular and parallel to the direction of wave motion.
Explanation: This is practically the answer the question below (or above me) tried to explain.
