East component: 3.9 m/s
South component: 1.8 m/s
Explanation:
We have to resolve the velocity vector along the east and south axis.
Taking east as positive x-direction and south as positive y-direction, the components of the velocity are given by:
where
v = 4.3 m/s is the magnitude of the velocity
is the angle between the direction of the velocity and of the x-axis
Substituting into the equations, we find:
East component:
South component:

Answer:
The magnetic field is 14.08 T.
Explanation:
Given that,
Speed of electron
Distance
Suppose we need to find the magnetic field at the location of the proton
We need to calculate the magnetic field
Using formula of magnetic field
....(I)
Using formula of current
Using formula of time
Put the value of current and time in equation (I)
Put the value into the formula
Hence, The magnetic field is 14.08 T.
Answer:
404K
Explanation:
Data given, Kinetic Energy.K.E=8.37*10^-21J
Note: as the temperature of a is increase, the rate of random movement will increase, hence leading to more collision per unit time. Hence we can say that the relationship between the kinetic energy and the temperature is a direct variation.
This relationship can be expressed as
where K is a constant of value 1.38*10^-23
Hence if we substitute the values, we arrive at
converting to degree we have
