{Impulse} is the product of force and the time during which the force acts. It is equal to the change in momentum of an object. Mathematically, \( J = F \cdot t = \Delta p \).
Impulse (\( J \)) is defined as the change in momentum of an object. It can be calculated using the formula: \[ J = \Delta p = m \cdot v \] where:
\( m \) is the mass of the bullet,
\( v \) is the velocity of the bullet.
Given: \[ m = 10 \, \text{g} = 0.01 \, \text{kg} \\ v = 600 \, \text{m/s} \] Substituting the values: \[ J = 0.01 \, \text{kg} \times 600 \, \text{m/s} = 6 \, \text{Ns} \] Therefore, the impulse supplied to the gun is \( 6 \, \text{Ns} \).
A black body is at a temperature of 2880 K. The energy of radiation emitted by this body with wavelength between 499 nm and 500 nm is U1, between 999 nm and 1000 nm is U2 and between 1499 nm and 1500 nm is U3. The Wien's constant, b = 2.88×106 nm-K. Then,
