Answer:
option A.
Explanation:
given,
Both swings are at the same height
Start swinging at the same time
The length of the string of your friend's string is longer than yours.
Using the formula of the time period
The time period is directly proportional to Length.
If the length of the string is less time period will be less.
So, your time period is less than your friend's.
Hence, when you will complete your swing your friend will be slightly lower than you.
Hence, the correct answer is option A.
The outer planets (Jupiter, Saturn, Uranus, Neptune) are called the "<u>GAS</u> giants".
The rocky planets are called "rocky" because they're made of <u>ROCK</u>.
Does this help guide you to the correct choice ?
Here's another hint: The MOST dense planet in our solar system, the one we call "Earth", is one of the 'rocky planets'.
Explanation:
work done =force *distance
work done =17000*26
work done=442,000 joules.
The experiments will involve two billiard balls of known masses, m₁ and m₂, and velocities u₁ and u₂. The two are allowed to collide and the velocities of the balls after the collision v₁ and v₂ are recorded.
The momentum before and after the collision is then calculated as follows:
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
<h3>What is the statement of the law of conservation of momentum?</h3>
The law of the conservation of momentum states that the momentum before and after collision in a system of colliding bodies is conserved
The momentum of a body is calculated using the formula below:
Momentum = mass * velocity.
Hence, for the two billiard balls, the momentum before and after the collision is conserved.
