Radiation and Convection transfer energy from the core to the photosphere. This is because energy from the core moves through a thick layer called the radiative zone. Also in the convection zone energy moves mainly by convection. Rising currents of hot gas in the convection zone carry energy toward the Sun's surface.
Answer:
B
Explanation:
Power is defined as the work done per unit time
The magnitude of the impulse delivered to the baseball by the bat is 8.8 Ns.
<h3>Impulse experienced by objects</h3>
The impulse experienced by any object is equal to the change in the momentum of the object.
The magnitude of the impulse delivered to the baseball by the bat is calculated by applying the following equation.
J = Ft
where;
- F is applied force = 8000 N
- t is time, = 1.1 ms
J = (8000) x (1.1 x 10⁻³)
J = 8.8 Ns
Thus, the magnitude of the impulse delivered to the baseball by the bat is 8.8 Ns.

Answer:
N = 177843 sheets
Explanation:
We are given;
Mass;m = 0.0035 kg
Pressure; p = 101325 pa = 101325 N/m²
L = 0.279m
W = 0.216m
The weight of N sheets is N(mg)
Where;
m is the mass of one sheet
N is number of sheets
g is the acceleration due to gravity.
The pressure equals weight divided by the area on which the weight presses:
Thus,
p= F/A = Nmg/(L•W)
Therefore, making N the subject;
N = pLW/(mg)
N = 101325 x 0.279 x 0.216/ (0.0035 x 9.81)
N = 177843
