There are different kinds of forces; applied force, force of gravity, friction force, normal force, tension force. We will focus on the common forces, applied force and force of gravity. An applied force is a force that is applied to an object by another object. The force of gravity is the force with which massively large objects such as the earth attracts another object towards itself. All objects of the earth exert a gravity that is directed towards the center of the earth. Therefore, the force of gravity of the earth is equal to the weight of the object.

A weather balloon is Floating at a constant height above Earth when it releases a pack hot instruments. If the pack hits the gro
Slav-nsk [51]

Answer:

The pack has fallen 275.6 m

Explanation:

The pack is in free fall, so it is moving by uniform accelerated motion, so we can use the following suvat equation:

v^2-u^2=2as

where, choosing upward as positive direction:

v is the final velocity

u is the initial velocity

a=g=-9.8 m/s^2 is the acceleration of gravity

s is the vertical displacement

For the pack in this problem,

u = 0

v = -73.5 m/s

Solving for s, we find how far the packet has fallen:

s=\frac{v^2-u^2}{2a}=\frac{(-73.5)^2-0^2}{2(-9.8)}=-275.6 m

And the negative sign means the direction of the displacement is downward.

A toy car has a 1.5 A current, and its resistance is 2 Ω. How much voltage does the car require?
Brums [2.3K]

Answer:

Battery Voltage

Explanation:

Voltage refers to the amount of electrical potential your battery holds. The standard automotive battery in today's vehicles is a 12-volt battery. Each battery has six cells, each with 2.1 volts at full charge. A car battery is considered fully charged at 12.6 volts or higher. hope this helps you :)

How much force is required to produce a torque of 100 Nm if the force is applied at an angle of 40 at a distance of 25 cm from t
Fudgin [204]

Answer:

Force, F = 622.28 N

Explanation:

It is given that,

Torque, \tau=100\ N-m

Angle between force and displacement, \theta=40^{\circ}

Distance, d = 25 cm = 0.25 m

We need to find the force required to produce the torque. Torque produced by an object is given by :

\tau=Fd\sin\theta

F is force required to produce torque

F=\dfrac{\tau}{d\sin\theta}\\\\F=\dfrac{100}{0.25\times \sin(40)}\\\\F=622.28\ N

So, applied force is 622.28 N.
