if its winter
Explanation:
then we know it will me cold
The sequence of energy transformations from the moment the ball is dropped to the moment the board is bent to its maximum extent and the ball is at rest is as follows:
1. The ball has potential energy (gravitational potential energy) from being held above the board.
2. As the ball is dropped, it gains kinetic energy as it accelerates to the ground.
3. When the ball hits the board, the kinetic energy is converted into elastic potential energy as the board bends.
4. As the board continues to bend, the elastic potential energy is converted into thermal energy.
5. Finally, when the board reaches its maximum extent, the ball is at rest and its kinetic energy has been completely converted into thermal energy.

Answer:
The Answer is 4.08 x 1023 Atoms (Choice B.)
Explanation:
The SI base unit for amount of substance is the mole.
1 mole is equal to 1 moles Helium, or 4.002602 grams.
1.02 moles would equal 4.08 x 1023

Answer:
The waves interfere destructively occur. The further explanation is given below.
Explanation:
The transmissions almost commute with either the speed of light. So, use the following relation to calculate the wavelength of that same TV signal.
⇒ λ =
⇒ =
⇒ =
The variance in the route between both the 2 waves that approach the recipient is 248 m, also because wave passes 124 m two times. And then after the plane's reflective thinking the waves iteration adjustments by half.
⇒ Δ = λ
If the value of the above expression is a positive integer, the waves interfere constructively, as well as the waves disrupt destructively if they are integral multiples of the half. Caused by a change of step due to the reflection the component of half would be added.
⇒
⇒
Since the value of m seems to be an integral multiple of the half.
Therefore, the waves interfere destructively
