Answer:
yes
Explanation:
the mantle rotates around the iron core and creates a charge. that charges radiates outward as the magnetosphere
Answer:
W = 0.060 J
v_2 = 0.18 m/s
Explanation:
solution:
for the spring:
W = 1/2*k*x_1^2 - 1/2*k*x_2^2
x_1 = -0.025 m and x_2 = 0
W = 1/2*k*x_1^2 = 1/2*(250 N/m)(-0.028m)^2
W = 0.060 J
the work-energy theorem,
W_tot = K_2 - K_1 = ΔK
with K = 1/2*m*v^2
v_2 = √2*W/m
v_2 = 0.18 m/s
On behalf of the state, write an invitation for the siblings for the gala dinner
Hello there, we would like to welcome you to the gala dinner hope you can come :)
You could try the "Spinning Bucket" or the "Center Of Gravity" experiment. There are plenty more that you could research! Hope this helped :)
Answer:
Explanation:
The force of kinetic friction on the block is defined as:
Where is the coefficient of kinetic friction between the block and the surface and N is the normal force, which is always perpendicular to the surface that the object contacts. So, according to the free body diagram of the block, we have:
Replacing this in the first equation and solving for :
