Answer:
2m/s
Explanation:
The formula for acceleration can be found by [ a = f/m ]
We are given the force [ 100N ] and the mass [ 50g ].
We can use these values to solve for the acceleration.
a = 100/50
a = 2m/s
Best of Luck!
Answer:
670400 J
Explanation:
m = mass of water = 2 kg
T₀ = initial temperature of water = 20 ºC
T = initial temperature of water = 100 ºC
c = heat capacity of water = 4190 J /kg ºC
Q = energy needed to raise the temperature of water
Energy needed to raise the temperature of water is given as
Q = m c (T - T₀)
Inserting the values
Q = (2) (4190) (100 - 20)
Q = 670400 J
The Doppler effect is when the frequency of a sound changes as the position of you and the sound changes. For example, if a fire truck comes at you, the siren sound will increase, then, after it passes you, then the sound will decrease. The thing that just happened is the Doppler effect!
Have a nice day! :)
Bursitis is when the small fluid filled sacs around the joints called bursae are irritated or injured. In just about any joint the effects can be felt with pain in movement and when pressed upon. Sometimes a rash will occurs as well. Thank you for posting your question here. I hope the answer will help. <span>

Answer:
ε = 6.617 V
Explanation:
We are given;
Number of turns; N = 40 turns
Diameter;D = 18cm = 0.18m
magnetic field; B = 0.65 T
Time;t = 0.1 s
The formula for the induced electric field(E.M.F) is given by;
ε = |-NAB/t|
A is area
ε is induced electric field
While N,B and t remain as earlier described.
Area = π(d²/4) = π(0.18²/4) = 0.02545
Thus;
ε = |-40 × 0.02545 × 0.65/0.1|
ε = 6.617 V
(we ignore the negative sign because we have to take the absolute value)
