Answer:
The tension in the rope is 49.66 N.
Explanation:
Given that,
Mass of bucket m= 23.0 kg
Diameter = 0.300 m
Mass of rope M= 13.0 kg
Height = 10.5 m
Suppose we need to find the tension in the rope while the bucket is falling.
We need to calculate the acceleration
Using balance equation
..(I)
We need to calculate the tension in the rope
Using formula of tension
....(II)
Put the value of T in the equation (I)
Put the value into the formula
Now, put the value of a in equation (II)
Hence, The tension in the rope is 49.66 N.
Answer:
electeicity is caused by the movement of. from one atom to the next
Answer:
See the explanation below
Explanation:
We must perform a sum of forces on the body, that sum of forces is equal to zero. That is, the body is in balance and does not move.
ΣF = 0
3 - 3 = 0
This force is negative and acts by pointing downwards.
Answer:
Explanation:
The equation of electric field is
E = 375 Sin(5.97 x 10^15 t + 1.99 x 10^7 x)
Compare with the standard equation
E = Eo Sin(ωt + kx)
(b) Amplitude of electric field, Eo = 375 V/m
Amplitude of magnetic field, Bo = Eo / c = 375 / (3 x 10^8)
Bo = 125 x 10^-8 Tesla
Bo = 1.25 x 10^-6 Tesla
(c) ω = 5.97 x 10^15 rad
2 x 3.14 x f = 5.97 x 10^15
f = 0.95 x 10^15 Hz
f = 9.5 x 10^14 Hz
Answer:
If we use a mixture of red and blue light, the blue toy car might reflect deep magenta color. If the toy car is made up of metal, it might reflect glittery magenta color. If the intensity of the blue color is greater, the toy car might show dark blue color
