A student pulls a 50-newton sled with a force having a magnitude of 15 newtons. What is the magnitude of the force that the sled

Simora [160]

Answer:

Force = 35 N

Explanation:

From Newton's third law of motion, the boy must apply a force greater than the weight of the sled to lift it.

weight of sled = mg

where m is its mass and g the force of gravity on it.

weight of sled = 50 N

Force applied by the boy on the sled = 15 N

Since the force applied on the sled by the boy is lesser than the weight of the sled, then;

Force that the sled exerts on the student = 50 - 15

= 35 N

The force exerted by the sled on the student is 35 N.

Which best describes a concave lens?

-Dominant- [34]

Answer:

Explanation:

Concave lens also called as diverging lens i.e. it diverges ray of light coming towards it.

Concave lens is thicker at the edges and thinner at the center.

Concave lens formed the virtual image of the object i.e. it cannot be trace on screen. This lens is used to treat the nearsightedness or myopia in which a person is unable to see the far object clearly.

A 12 kg barrel is pulled up by a rope. The barrel accelerates at 1.2 m/s2. Find the force exerted by the rope. Show all your wor

IgorLugansk [536]

Answer:

F = 132N

Explanation:

Let the pulling force be F

Given the mass of the barrel is 12 Kg and The acceleration is 1.2 m/ $sec^2$

We know that Net Force = $mass\times acceleration$

Now net force = F - mg

F - mg = ma

F = mg + ma

F = m(a+g) = $12\times (1.2 +9.8)=132N$

Note that there will be a downward force acting on the body which is equal to mg
