The height of the cliff is <u>80 meters.</u>
The rate of change of position of an item in any path. The speed is measured because of the ratio of distance to the time in which the distance was included.
Velocity can be the concept of the charge at which an item covers distance. a quick-shifting item has a high pace and covers a highly huge distance in a given quantity of time, whilst a sluggish-shifting object covers a fantastically small quantity of distance in an identical amount of time.
Motion is a change in the function of an object over the years. motion is defined in terms of displacement, distance, speed, acceleration, time, and speed. speed, being a scalar amount, is the fee at which an item covers distance with respect to time.
Calculation:-
Time = distance/ speed
= 30/15
= <u>2 seconds.</u>
S = ut + 1/2 at²
= 30 × 2 + 0.5 × 10 × 4
= 60 + 20
=<u> 80 meters.</u>

Explanation:
Answer:
The energy value is expected to rise steadily until it is equal to a value that depends on the temperature T of the environment.
Explanation:
If a system is immersed into an environment with a constant high temperature, the temperature of the system will also rise until it comes to equilibrium with the temperature of the environment. When this happens, the energy expectation value of the system will now be dependent on the temperature of the environment. This means that the energy of the system will be a function of the temperature of the environment.
This means that
E = f(T)
where E is the energy value of the system
T is the temperature of the environment.
Ok this is probably the easiest part in physics so lol dont panic. now the way you round is by looking at the exponent which in this case for the first one is -9 so 6.8 is gonna be 0000000068. because when you have a negative exponent you move the decimal to the west side. when you have a positive decimal you move to the east side. I will not do the second one because its best if you try to solve it so you can learn it. good luck my friend.
