Answer:
increase speed, decrease speed, and change direction
Explanation:
Using the two kinematic equations that can be used for this problem are:
Vf = Vi + at and d=Vit +(1/2)*at^2
Since Vi (initial velocity) = 0
The equations can further be simplified where a is the acceleration, t is the time, Vf is the final velocity which is 70 miles per hour and d is 6 miles
Vf = at
70 = at
a = 70/t---equation 1
d=(1/2)*a*(t^2)
6 = (1/2)*a*(t^2) ---equation 2
Substituting equation 1 to equation 2.
6= (1/2)*(70/t)*(t^2)
6= 35t
t= 0.17142 hours or 10.28571 mins or 617.14 sec
Answer:
Explanation:
Given that,
The magnitude of vector A, 
The magnitude of vector B, 
Scalar product of A and B, 
The formula for the scalar product is given by :
Where, 
is the angle between A and B.
The formula for the vector product is given by :
So, the vector product between these two vectors is 
.
The amplitude of wave-c is 1 meter.
The speed of all of the waves is (12meters/2sec)= 6 m/s.
The period of wave-a is 1/2 second.
The electric magnet (Electromagnetic) is temporary because you can turn it on and off. When it's power source is gone, the magnet becomes useless. Usually it's power source is a battery, but it could be solar with a switch. Hope this helps. Please give me brainliest is this helps you.
