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:
18joules
Explanation:
1/2 of 4=2
2 multiply by 9= 18 joules
Answer:
a) 
= 4.67m/s
b) V = 8.29 m/s
Explanation:
Givens:
The bullet is 5.30g moving at 963m/s and its speed reduced to 426m/s. The wooden block is 610g.
a) From conservation of linear momentum
Pi = Pf
where 
are the mass and the initial velocity of the bullet, 
and 
are the mass and the initial velocity of the wooden block, and and 
are the final velocities of the wooden block and the bullet
The wooden block is initial at rest 
this yields
By solving for adn substitute the givens
= 
= 
= 4.67m/s
b) The center of mass speed is defined as
substituting:
V = 8.29 m/s
E=F*d/2 = M*g*d/2 = 25kg * 9.8 N/kg *0.65m / 2 = 79.625J
