Explanation:
Formula to calculate the electric field of the sheet is as follows.
E = 
And, expression for magnitude of force exerted on the electron is as follows.
F = Eq
So, work done by the force on electron is as follows.
W = Fs
where, s = distance of electron from its initial position
= (0.570 - 0.06) m
= 0.51 m
First, we will calculate the electric field as follows.
E =
= 
= 0.259 N/C
Now, force will be calculated as follows.
F = Eq
= 
= 
Now, work done will be as follows.
W = Fs
= 
= 
Thus, we can conclude that work done on the electron by the electric field of the sheet is .
Answer:
C. 233 km/h
Explanation:
Ground speed = air speed + wind speed
250 km/h = v + 17 km/h
v = 233 km/h
I believe the correct answer is the third option. One advantage of using lasers in cutting patterns instead of traditional cutting machines would be that lasers save time by cutting through more layers of fabric. Although it would cost some energy and the initial cost would be high, you would still be able to save some money as time goes by since you will be able to produce more for a certain period of time as compared to using traditional cutting methods for the same period of time. Also, by using lasers, you can cut complex patterns easily and you will need less people in the production.
Answer:
torque = 3.897 N-m
Explanation:
given data
force = 300 N
angle = 60 degree
distance = 15 cm
to find out
torque
solution
we will apply here torque formula that is given below
torque = force × sinθ × distance ...................1
put here all these value in equation 1
we get torque
torque = force × sinθ × distance
torque = 300 × sin60 × 1.5 ×
torque = 300 × 0.8660 × 1.5 ×
torque = 259.80 × 1.5 ×
torque = 389.711 ×
torque = 3.897 N-m
