the answer is speaker it transform electrical energy into sound energy
Answer:
a) 378Ns
b) 477.27N
Explanation:
Impulse is the defined as the product of the applied force and time taken. This is expressed according to the formula
I = Ft = m(v-u)
m is the mass = 70kg
v is the final velocity = 5.4m/s
u is the initial velocity = 0m/s
Get the impulse
I = m(v-u)
I = 70(5.4-0)
I = 70(5.4)
I = 378Ns
b) Average total force is expressed as
F = ma (Newton's second law)
F = m(v-u)/t
F = 378/0.792
F = 477.27N
Hence the average total force experienced by a 70.0-kg passenger in the car during the time the car accelerates is 477.27N
Answer:
4 m/s
Explanation:
If you pick the points (2,8) and (3,12) on the graph, y2-y1 over x2-x1, you get 4 over 1 which equals 4.
Answer:
d. N*m
Explanation:
Workdone which is measured in Joules is calculated using the formula;
Workdone = force * distance
Where;
Force is measured in Newton
Distance is measured in meters.
Therefore, workdone also has the measurement of Newton-meters.
