A car traveling initially at 7.35 m/s acceler-
1 answer:
Answer:
Explanation:
<u>Constant Acceleration Motion</u>
It's a type of motion in which the velocity of an object changes uniformly in time.
Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:
The car initially travels at vo=7.35 m/s and accelerates at a rate of during t=2.09 s.
The final velocity is:

Voltage,
De broglie wavelength in terms of voltage is given by :
m and e are the mass and charge on electron. So,
So, the De broglie wavelength of an electron is 1.53 meters. Hence, this is the required solution.
Answer:
No. of 100 W bulbs, n = 28,539 bulbs
Given:
Power of a single bulb = 100 W
Time period, T = 1 yr = = 31,536,000 s
mass of matter, m = 1 g =
Solution:
According to Eintein's mass-energy equivalence:
E =
E =
E =
