Answer:
Explanation:
decrease in energy of the transferred charge
= Voltage x charge
= 2.86 x 10⁹ x 23.1
= 66.067 x 10⁹ J
the final speed of the automobile be V
1/2 m v² = 66.067 x 10⁹
v² = 66.067 x 10⁹ x 2 / 1519
= .08698 x10⁹
= 87 x 10⁶
v = 9.32 x 10³ m / s
Answer:
The Force exerted by the two objects will be same and 4,401,189.49 × 10−11 N
Explanation:
Let m1 be the mass of the first object and m2 be the mass of the second object and the distance between them be d. Then
m1= 181kg
m2= 712 kg
d= 0.442 m
G is the gravitational Constant
According to Newtons Law Gravitational Force is given by
F=G m1 m2 /d²
F= 6.672 × 10−11 ×181×712/(0.442)²
F= 859,576.24 × 10−11/0.195364
F= 4,401,189.49 × 10−11 N
The Force exerted by the two masses on the third mass will be same and 4,401,189.49 × 10−11 N
Punching a bag is a suitable example of the situation when the force applied to change shape of an object.
Answer:
through reading the question carefully and using yourself as an exampke
Answer:
375 ms
Explanation:
the frequency of metronome , f = 160 beats per minute
f = 160 /60 beats per sec
f = 2.67 beats /s
the period of a single beat , T = 1/f
T = 1/2.67 s
T = 0.375 s = 375 ms
the period of a single beat is 375 ms
