Answer:
The cathode ray is deflected vertically to the fluorescent screen
Explanation:
Acceleration = (change in speed) / (time for the change)
Acceleration = (4 m/s) / (8 seconds)
Acceleration = 0.5 m/s²
Force = (mass) x (acceleration)
Force = (85 kg) x (0.5 m/s²)
Force = 42.5 Newtons
Answer:
a. Exactly the same as the magnitude of the charge of the proton.
Explanation:
The elementary charge (e) is the smallest electric charge that can exist in the universe. Any positive or negative electric charge can be expressed as a multiple of the elementary charge, since is the electric charge carried by a single proton or, equivalently, the magnitude of the electric charge carried by a single electron (-1e).
Answer: D. meter, kilometer
SI or "International System of Unit" is the unit that used in the international organization to make counting easier.
In this case, all of the options are base SI but if you compare them both they are a different unit that can't be converted each other. You can't convert gram into second.
Only option D. meter, kilometer is had the same unit that can be converted.
Answer:
230.53°
Explanation:
α = angle in rad / t^2
t =2mins = 2 × 60 = 120sec.
α = angle in rad / 2^2
α = angle in rad / 16
15+4(2) = angle in rad /4
23 = angle/4
23× 4 = angle in radian
92 = angle in radian
But π rad = 180°
1 rad = 180 /π
Therefore
92 rad = 92 ×180/π = 5270.53°
This value is far more so we subtract from 360° continuously till we get a value less than 360°
5270.53- (360×14) =5270.53- 5040
230.53°
