8 meters per second. To find velocity is to divide distance by total time. so 400/50.
If you insert a crimp pin incorrectly, the ratcheted crimp tool will not sufficiently crimp the tabs. As a result, the wire may not fully conduct with the pin and the pin will be damaged.
<u>Explanation:</u>
The general theory for crimping all types of connectors is to strip a little bit of insulation off the wire. Then, put the connector into a suitably sized space in the jaws, insert the wire, and crimp it down. For non-ratcheting pliers, it's suggested the connector be re-crimped with the next smallest hole in the jaws.
A good crimp connection is gas tight and won't wick: it is sometimes referred to as a “cold weld”. Like the solder method, it can be used on solid or stranded conductors, and provides a good mechanical and electrical connection.
Answer:
The velocity of the police car relative to earth is 
Given:
time for flash generation of the inter galactic police car, t = 1.2 s
time between flashes as measured from earth, t' = 2.2 s
Solution:
Utilising Einstein's equation for time dilation to calculate the velocity of the police car, the equation is given by:
(1)
where, c = speed of light in vacuum = 
re arranging eqn (1) for velocity, v:
(2)
Now, from eqn (2)
Answer:
a) in uniform motion
Explanation:
When velocity-time graph is parallel to x-axis, it shows that the object is moving with constant velocity. or we can say that that the object is moving with uniform motion. There is no change in velocity. It covere equal distance in equal intervals of time.
Hence, the correct option is (a) "in uniform motion".
