Answer:
5 m/s
Explanation:
Given that,
A vehicle is moving with 20m/s towards the east and another is moving 15m/s towards the west.
It is assumed to find the resultant velocity of the vehicle. Let east side is positive and west is negative. So,

Hence, the resultant velocity of the vehicle is equal to 5 m/s.
In addition to visible light, radio, some infrared and a very small amount of ultraviolet radiation also reaches the Earth's surface from space. ... Infrared waves have wavelengths longer than visible and shorter than microwaves, and have frequencies which are lower than visible and higher than microwaves.
First, you should convert the initial and final velocities from km/h to m/s. You should end up with Vi= 25m/s and Vf=10m/s (both rounded).
Now, you can use the equation Vf=Vi+A(t)
Rearrange it to A is isolated: A= Vf-Vi/t
A=(10-25)/6
A=-2.5m/s^2
Answer:
electrons
Explanation:
Because electric current is flowed due to the presence of free electrons.
