A bomb of mass 6kg initially at rest explodes into two fragments of masses 4kg and2kg respectively. If the greater mass moves wi
1 answer:
Answer:
v = 10 [m/s]
Explanation:
The largest mass is that of 4 [kg], in this way the momentum can be calculated by means of the product of the mass by velocity.
where:
P = momentum [kg*m/s]
m = mass = 4 [kg]
v = velocity = 5 [m/s]
Now the momentum:
This same momentum is equal for the other mass, in this way we can find the velocity.

Power is the rate at which energy is consumed. When 1 J of energy is consumed in one second, the power consumed is 1 watt.
The microwave consumes 1.5 kJ of energy.
In joules, the energy consumed is 1500 J
Here, E is the energy consumed in time interval <em>t.</em>
The power rating of the microwave is therefore,
Thus, the power rating of the oven is 1500 W or 1.5 kW
Answer:
Explanation:
As we know by the formula of diffraction
so we have
a = slit size
= angular position of Nth minimum
so we will have
for first minimum of 630 nm light
Now for another wavelength second minimum is at 60 degree angle
