Answer:
Momentum, p = 34.937 kg-m/s
Explanation:
It is given that,
Force acting on the bowling ball, F = 48.2 N
Velocity of bowling ball, v = 7.13 m/s
We have to find the momentum of the ball. Momentum is given by :
p = mv........(1)
Firstly, calculating the mass of bowling ball using second law of motion. The force acting on the ball is gravitational force and it is given by :
F = m g (a = g)
m = 4.9 kg
Now putting the value of m in equation (1) as :
p = 34.937 kg-m/s
Hence, this is the required solution.
(a) Does an electric field exert a force on a stationary charged object? YES ( F = Eq)
(b) Does a magnetic field do so?- NO ( F= qvB)
(c) Does an electric field exert a force on a moving charged object? YES
(d) Does a magnetic field do so? YES ( F = qvB)
(e) Does an electric field exert a force on a straight current-carrying wire? ( NO)
(f) Does a magnetic field do so? Yes
(g) Does an electric field exert a force on a beam of moving electrons? Yes
(h) Does a magnetic field do so? YeS

38*10=380 N
To be more exact, 38 should be multiplied by 9.8 instead of 10.
Answer:
344.8 x10^-8J/m³
Explanation:
Using=> energy intensity/ speed oflight
= 1000/2.9x10^8
= 344.8 x10^-8J/m³
In exothermic/exergonic reactions, reactants have greater energy(Gibbs-Free Energy) than the products. This energy determines how much mechanical work a system can do
