Answer:
Solar radiation
Explanation:
Visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.
Acceleration = change in velocity divided by time taken...
I.e Acceleration = (Final velocity - Initial Velocity) /time taken...
The question says the body accelerate from rest... Therefore it's initial velocity = 0
It reach a speed(velocity) of 20m/s.. My final velocity
And the time taken to attain the velocity = 5 seconds....
Therefore
acceleration = (20-0)/5
a = 20/5
a = 4ms¯²
Hope this helped....
First we have to convert 6 grams to kg (0.006 kg) and then using the thermal physics formula which is Q=m*c*change in temperature, we get 478,8 joule
(Btw c is the specific heat capacity of water which is 4200 j/kg °C
Answer: B false
Explanation: This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another. For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes.
Answer:
It's neutral.
Explanation:
Neutral has an equal proportion of acid and alkali which makes the pH between 0-14 which is 7.
