Answer:
Explanation:
mass of proton, m = 1.67 x 10^-27 kg
speed of proton, v = 350 km/s = 350,000 m/s
Momentum of proton, p = mass x speed
p = 1.67 x 10^-27 x 350000 = 5.845 x 10^-22 kg m /s
uncertainty in momentum, Δp = 0.1 % of p
Δp = 
According to the principle
where, Δx be the uncertainty in position
Answer:
1. Static electricity is caused by the build up of electrical charges on the surface of objects, while current electricity is a phenomenon from the flow of electrons along a conductor.
Explanation:
Answer:
Their efforts would be expressed in units of Joules per second
Explanation:
The unit of their efforts can be derived from the formula of power which is given by the product of mass, acceleration and distance (the product is energy with unit joules) divided by time taken to complete the task (unit is seconds)
Therefore, the unit of their efforts would be joules per second
The first one is conduction and the second one is radiation
The direction of a vector multiplied by a scalar is only affected if the scalar is negative, in which case the vector will now be in the opposite direction. If the scalar is positive, the vector will only change in magnitude
