Approximately 80% of the energy used for active transport is devoted to the reabsorption of sodium. Hope this helped, have a great day! :D
Answer:
According to the right-hand rule, the magnetic field is into the page.
Explanation:
According to the right-hand rule, the magnetic field is into the page. According to this rule, if the middle finger points in the direction of initial motion of the charge as it enters the magnetic field to the right, and point the thumb and index finer perpendicular to each other and the middle finer perpendicular to the index finer. We then point the middle finger to the right in the direction of motion of the proton. If we are to have a clockwise force on the proton in the plane of the page, the thumb must point parallel to the page, downwards towards the south. The direction of the index finger is thus the direction of the magnetic field, and this is into the page.
Voltage of each component is same.
The force used to kick the ball is 1000N
The mass of the ball is 0.8 kg
Time is 0.8 seconds
Therefore the velocity can be calculated as follows
F= Mv-mu/t
1000= 0.8(v) - 0.8(0)/0.8
1000= 0.8v- 0.8/0.8
Cross multiply both sides
1000(0.8) = 0.8v
800= 0.8v
divide both sides by the coefficient of v which is 8
800/0.8= 0.8v/0.8
v= 1000m/s
Hence the velocity is 1000m/s
<u>Complete Question:</u>
A hockey player swings her hockey stick and strikes a puck. According to Newton’s third law of motion, which of the following is a reaction to the stick pushing on the puck?
A. the puck pushing on the stick
.
B. the stick pushing on the player
.
C. the player pushing on the stick
.
D. the puck pushing on the player.
<u>Correct Option:</u>
According to Newton’s third law of motion the puck pushing on the stick is a reaction to the stick pushing on the puck.
<u>Option: A</u>
<u>Explanation:</u>
As when the hockey exert force on the puck (which is a flat ball basically used in ice hockey) then this action by hockey will receive equal and opposite reaction by puck. Thus when the stick is pushing on the this flat ball, then puck also push the stick. This is understood by newton's third law pf motion, where action and reaction forces are subject of discussion, displaying their is pair of forces applied among the interacting objects. This form is observed more practically in life and very frequent.
