☄ <u>Universal</u><u> </u><u>Gravitational</u><u> </u><u>Constant</u><u>(</u><u>G</u><u>)</u>
Gravitational constant is a constant of proportionality when F(Gravitational force) is proportional to product of masses and inversely proportional to the distance between them.
- It can be defined as:- Universal gravitational constant is the magnitude of the force between a pair of 1 kg masses that are kept 1 metre apart.
- The SI unit of G is N m²/kg² and the CGS unit of G is Dyne cm² / g².

The value of G (universal gravitational constant) was found out by the scientist Henry Cavendish by using the sensitive torsion balance

Answer:
The maximum height the pumpkin reaches occurs at 62.5 horizontal meters from its launching spot.
Explanation:
Notice that we are given the actual trajectory equation:
which corresponds to a curve represented by a parabola.
We can find the maximum of this parabola with arms pointing down requesting the derivative (slope of the tangent line to the curve) to be zero :
Atomic disguise makes helium look like hydrogen. ... A helium atom consists of a nucleus containing two positively charged protons and two neutrons, encircled by two orbiting electrons which carry a negative charge. A hydrogen atom has just one proton and one electron
The answer is Gravity
There's always a gravity between any 2 objects in this universe. between you and your computer, between you and the floor, between your chair and your table, etc.
We just dont feel it because we live in earth which negates all of those gravities with its own.
Answer: 317.0 m/s
Explanation:
The motion of the bullet is a projectile motion, with:
- a uniform motion with constant speed v along the horizontal direction
- an accelerated motion with constant acceleration toward the ground
We know that the starting height of the bullet is h=1.4 m. If we consider the vertical motion only, the initial velocity is zero, so we can write:
The bullet reach the ground when y(t)=0, so the time taken is
During this time, the bullet travels d=168 m horizontally, so its horizontal speed (which is equal to the initial speed of the bullet) is given by
