Given that, A basesball is dropped from 100 meters above the surface of the earth. If the same baseball was dropped from 100 meters above the surface of the moon, it will take more time to hit the ground as compare to the ball dropped on earth. This is moon's gravity is one-sixth of that of earth. Object falling on earth possess more force of attraction. So it will reach the earth in lesser time. At moon the force of attraction is low compare to that of earth. Object will take more time to reach the surface.
Answer:
I literally just got done doing something like this in my physic class. The resistance is 9.6 ohms.
Answer:
The vertical velocity of the skater upon landing is 10.788 meters per second.
Explanation:
Skateboarder experiments a parabolic movement. As skateboarder jumps horizontally off the top of the staircase, it means that vertical component of initial velocity is zero and accelerates by gravity, the final vertical speed is calculated by the following expression:

Where:
- Initial vertical speed, measured in meters per second.
- Final vertical speed, measured in meters per second.
- Gravitational acceleration, measured in meters per square second.
- Time, measured in seconds.
Given that
,
and
, the final velocity of the skater upon landing is:


The vertical velocity of the skater upon landing is 10.788 meters per second.
Answer:
The energy goes from <u>the ground state</u> to <u>the excited states</u> above it.
Force of gravity = 'G' (mass₁)(mass₂) / (distance)²
'G' is the gravitational constant for SI units = 6.67 x10⁻¹¹ newton-meter²/kg²
You said that the force is <u>2.99 x 10⁻¹⁰</u> = (6.67x10⁻¹¹) (4) (7) / D²
Multiply each side by D² : 2.99 x 10⁻¹⁰ D² = (6.67x10⁻¹¹) (28)
Divide each side by 2.99 x 10⁻¹⁰ : D² = (28) (6.67 x10⁻¹¹) / (2.99 x 10⁻¹⁰)
Take the square root of each side: D = square root of all that
Stuff it through my calculator:
D = square root of [ (28) (6.67 x10⁻¹¹) / (2.99 x 10⁻¹⁰) ] =
√ ( 6.2462...) meters² =
<em>2.5 meters </em> (rounded)

To get the feel:
-- The book weighs about 8.8 pounds (big book)
-- The lamp weighs about 15.4 pounds
-- They're about 8.2 feet apart.
-- The strength of the gravitational force
