State an advantage of using such hydraulic jack to lift a load ​

Physics
1 answer:
expeople1 [14]2 years ago
5 0

Answer:

Explanation:

You are going to lift and press down on the 200 N many times and move only a short distance. The reward is that slowly but surely you will lift a very heavy load -- one that cannot be managed any other way but by the hydraulic jack.

A pelican flying along a horizontal path drops
Ludmilka [50]

Answer:

The initial speed of the pelican is 8.81 m/s.

Explanation:

Given;

height of the pelican, h = 5.0 m

horizontal distance, X = 8.9 m

The time of flight is given by;

t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2*5}{9.81} } \\\\t = 1.01 \ s

The initial horizontal speed of the pelican is given by;

X = vₓt

vₓ = X / t

vₓ = 8.9 / 1.01

vₓ = 8.81 m/s

Therefore, the initial speed of the pelican is 8.81 m/s.

Gravity pulled materials together forming the planets in our solar system. The inner planets consist of dense material, such as
Ede4ka [16]

Scientist identify the process in which gravity pulled materials together forming the planets in our solar system as accretion.

Accretion is the formation model of planets in our solar system in which gravity pulls materials together forming the planets.

This formation model accounts for the formation of the inner planets made of of dense material such as iron. These planets include Mercury, venus, earth etc.

As the gravity pulls in the more dense material, the less dense material such as ice, liquid and gas colect together to form the outer planets, which include Jupiter, Uranus, etc.

So, Scientist identify the process in which gravity pulled materials together forming the planets in our solar system as accretion.

Does latitude has an effect on weight? PLEASE HELP!​
kotegsom [21]

Answer:

yes

it does you weigh less on the equator than at the North or South Pole, but the difference is small. Note that your body itself does not change. Rather it is the force of gravity and other forces that change as you approach the poles. These forces change right back when you return to your original latitude.
