In the textbook the kind of idealized object that described in section on radiation laws that it absorbs all the radiation falling for it because it is not giving off any radiation on its own. And about the black sweater worn by one of your classmates it goes the same.
Answer:
formula used K=F/∆l
∆l is the elongation of the spring
- F=10N
- ∆l=20mm===> 0.02m
- K=10N divided 0.02m= 500N/m
The skateboard that has the greatest impulse is Skateboard C (Impulse = 25.74 Ns)
From the question,
We are to determine which skateboard has the greatest impulse. To do this, we will calculate the impulse of each skate board.
Impulse can be calculated by using the formula
I = Ft
Where I is the impulse
F is the force
and t is the time
Force = 33 N
Time = 0. 12 s
∴ Impulse = 33 × 0.12
Impulse = 3.96 Ns
Force = 33 N
Time = 0. 57 s
∴ Impulse = 33 × 0.57
Impulse = 18.81 Ns
Force = 33 N
Time = 0. 78 s
∴ Impulse = 33 × 0.78
Impulse = 25.74 Ns
Hence, the skateboard that has the greatest impulse is Skateboard C (Impulse = 25.74 Ns)
