Describes how a simple machine can make work easier?

Answers

simple machines such as ramps lessen the moment required to do work. if a triangle has a base of 5 and the height is 7, a ramp would make the hypotenuse of this triangle lessoning the total distance. using a²+b²=c² 25+49=c² 74≈8.6 and it is obvious that 8.6 is less than 12 in every unit. other simple machines such as pulleys make it lighter making it simply easier for an object to be lifted.

In a posteroanterior (pa) projection of the chest being used for cardiac evaluation, the heart measures 14.7 cm between its widest points. if the magnification factor is known to be 1.2, what is the actual diameter of the heart?

Answers

The actual diameter of the heart is 12.25 cm. Given : Heart measure = 14.7 cm Magnification factor = 1.2

14.7 / 1.2 = 12.25

A 15g bullet travelling at 100m/s strikes and is absorbed by a 75kg object. Find the speed at which the final object moves.

Answers

The final object will move with a speed of 1.9 x 10⁻² m/s.

What is law of conservation of momentum ?

According to the law of conservation of momentum, when two objects meet in a closed system, the sum of their momentums before and after the collision is constant.

Here,

Initial velocity of the bullet, u = 100 m/s

Mass of the bullet, m = 15 g = 0.015 kg

Mass of the object, M = 75 kg

Total momentum before collision, P₁ = mu + (M x 0)

P₁ = 0.015 x 100

P₁ = 1.5 Kgm/s

Total momentum after collision, P₂ = (m + M)v

P₂ = (0.015 + 75)v

P₂ = 75.015 v

According to law of conservation of momentum,

P₁ = P₂

1.5 = 75.015 v

Therefore, the speed with which the final object moves,

v = 1.5/75.015

v = 1.9 x 10⁻² m/s

Hence,

The final object will move with a speed of 1.9 x 10⁻² m/s.

The force of gravity on you is greatest when you are standing _____.a. far above Earth's surface
b. just above Earth's surface
c. on Earth's surface

Answers

The acceleration of gravity at the surface of the Earth is approximately 9.8 meters (32 feet) per second per second. As a result, during free fall, an object's speed rises by around 9.8 meters per second.

Explain about the force of gravity?

The force that binds all masses in the universe together, particularly the pull of the earth's mass on objects that are close to its surface.

The term gravitational force refers to the force that the earth exerts on a body. Examples of motion caused by gravitational force include the downward motion of water in a river, the downward motion of water in a stream, and the upward motion of a ball when it is thrown.

All physical things with mass are drawn to the gravitational force, which can be thought of as an attracting force. It is the known natural force that is by far the weakest. representation in mathematics. The formula for gravitational force is F = G m 1 m 2 r in mathematics.

The answer is on earth surface
