Answer:
v = 2591.83 m/s
Explanation:
Given that,
The electric field is 1.27 kV/m and the magnetic field is 0.49 T. We need to find the electron's speed if the fields are perpendicular to each other. The magnetic force is balanced by the electric force such that,
So, the speed of the electron is 2591.83 m/s.
Answer:
(A) Original velocity will be 7.244 m /sec
(B) Acceleration will be
Explanation:
We have given distance covers by truck s = 40 m
Time taken by truck to cover this distance t = 7.45 sec
Final velocity v = 3.50 sec
According to second equation of motion
-----eqn 1
According to first equation of motion
v = u + at
So -----eqn2
Solving equation 1 and 2
a =
And u = 7.244 m /sec
(A) Original velocity will be 7.244 m /sec
(B) Acceleration will be
Answer:4.05 s
Explanation:
Given
First stone is drop from cliff and second stone is thrown with a speed of 52.92 m/s after 2.7 s
Both hit the ground at the same time
Let h be the height of cliff and it reaches after time t
For second stone
---2
Equating 1 &2 we get
