Answer:
lymph Nodes
Explanation:
A mass of lymphatic tissue that help protect the body by removing foreign material such as bacteria and tumor cells from the lymphatic stream and by producing lymphocytes that function in the immune response
Answer: 42.95m/s
Explanation:
The magnitude of the force of the spring is given as
kx = 166N
From the question, we know that x = 60cm = 0.6m
Then, the constant of the spring would be k = 166/0.6 = 276.7N/m
When the bow is pulled back 60cm, the potential energy of the arrow is.
PE = 1/2kx²
PE = 0.5 * 276.67 * 0.6²
PE = 49.8J
Finally, the speed of the arrow can be found by using principle of conservation of energy, that states that, the total energy of an isolated system remains constant and conserved over time. This means, energy is neither created nor destroyed.
1/2kx² = 1/2mv²
kx² = mv²
v² = kx²/m
v² = 276.67 * 0.6²/ 0.054
v² = 1844.5
v = 42.95m/s
Answer:
This is because The glass rod of the electroscope is an insulator therefore only charge transferred to the ball is at the point of contact on the rod. Thus, When the charge rod is dragged across the top of the electroscope, by the experienced teacher the more charge is transferred to electroscope thereby producing a greater effect
The Sun is 864,400 miles across. its about 109 times the diameter of Earth<span>. so the volume is about 109 times the volume of the earth.</span>
