F=ma**2
a=sqrt (F/m)
a=sqrt8.3, which approximately is 3.
So acceleration equals 3 meters per sec**2.
The answer is DC power had to be converted in AC.
DC power is not usually in home. DC current must be converted to to AC, which is the standard in homes and to avoid short circuits.
DC or direct current explains the basic idea of electricity as a flow of electrons.
AC, also known as alternating current, electricity switches direction around 50-60 times each second. In here, electrons do not necessarily have to run in circles to transport energy, they simply run on the spot.
Answer:
The light rays falling on a rough surface does follow the laws of reflection. The light rays are incident parallel on the rough surface but due to uneven surface the light rays are not reflected parallel rather they are reflected in different direction. Hence, no image is formed.
<span>CH4 I assume you're doing a test or something but I'm not good at explaining things so hopefully it's multiple choice! </span>
Answer:
1 greater distances fallen in successive seconds
Explanation:
When a body falls freely it is subjected to the action of the force of gravity, which gives an acceleration of 9.8 m / s2, consequently, we are in an accelerated movement
If we use the kinematic formula we can find the position of the body
Y = Vo t + ½ to t2
Where the initial velocity is zero or constant and the acceleration is the acceleration of gravity
Y = - ½ g t2 = - ½ 9.8 t2 = -4.9 t2
Let's look for the position for successive times
t (s) Y (m)
1 -4.9
2 -19.6
3 -43.2
The sign indicates that the positive sense is up
It can be clearly seen that the distance is greatly increased every second that passes
