Answer:
She should drop two balls with different masses from the same height
Explanation:
Choices 'C' and 'D' are both correct.
(Except in 'C', changing the temperature from 1°C to 3°C is not usually
described as 'cooling', and it's not the water's 'mass' that changes. But
water does contract in volume during that change.)
We know,
V= f× wavelength
10.5= f×0.15
f=10.5/0.15
f= 70 Hz
Momentum = mass x velocity
So both mass and velocity affect an object's momentum.
Answer:
dorsiflexion
Explanation:
To decrease the angle between the anterior surface of the foot and anterior surface of the lower leg is described as: dorsiflexion
