Answer:
The energy required to accelerate an electron is 0.582 Mev and 0.350 Mev.
Explanation:
We know that,
Mass of electron 
Rest mass energy for electron = 0.511 Mev
(a). The energy required to accelerate an electron from 0.500c to 0.900c Mev
Using formula of rest,
(b). The energy required to accelerate an electron from 0.900c to 0.942c Mev
Using formula of rest,
Hence, The energy required to accelerate an electron is 0.582 Mev and 0.350 Mev.
Answer:
If you know the current and voltage across the whole circuit, you can find total resistance using Ohm's Law: R = V / I.
Explanation:
Answer:
v = 5.949 m / s
, a = 59.18 m / s²
Explanation:
Linear and angular quantities are related
v = w r
we search the magnitudes to the SI system
w = 95 rev / min (2π rad / 1rev) (1 min / 60 s) = 9.948 rad / s
d = 598 mm = 0.598 m
a) let's calculate the linear velocity
v = 9.948 0.598
v = 5.949 m / s
b) Cenripetal acceleration
a = v² / r
a = 5.94 2 / 0.598
a = 59.18 m / s²
Answer:
30 N
Explanation:
there are two forces act on the bar:
- weight of 1.5 kg mass, w = mg = 15 N
- weight of the bar, wb
for balance,
w * Lw = wb * Lwb
Lw = length of bar from the mass to the pivot
Lwb = lenght of bar from the center of the bar to the pivot
15 * 20 = wb * (50-20)
300 = wb * 30
wb = 300/30 = 30 N
