The buoyant force that acts on a floating 2000-N atmospheric science balloon is _______.

1 answer:

4 0

In this case, there are two forces that acts on the atmospheric science balloon. It is the force due to gravity or the weight and the buoyant force. A system at equilibrium should have the forces acting upon it equal. Therefore, the buoyant force would be equal to 2000N.

A 0.2 kg plastic cart and a 20 kg lead cart both roll without friction on a horizontal surface. Equal forces are used to push bo

Fynjy0 [20]

Answer:

Equal

Explanation:

The impulse theorem states that the impulse exerted on each cart is equal to the change in momentum of the cart:

$I=\Delta p=p_f -p_i$

where

I is the impulse

pf is the final momentum

pi is the initial momentum

The impulse is equal to the product between the force applied and the contact time:

$I=F\Delta t$

In this case, the force applied to the two carts (F) is the same, and the contact time ( $\Delta t$ ) is the same as well. Therefore, the impulse exerted on the two carts is the same.
