Answer:
28.3 kg
Explanation:
Assuming the ground is level, the normal force equals the weight.
N = mg
277 N = m × 9.8 m/s²
m = 28.3 kg
Im not quite sure but it might be a or c... ill double check
Answer:
The change in momentum (in kg*m/s) = 42
Explanation:
The change in momentum is equal to
Final Momentum - Initial Momentum
As we know
Momentum is equal to the product of mass and velocity
where m is the mass of the body and v is the speed
Thus, change in momentum
here m1 = m2 = 6 Kg
Substituting the given values in above equation we get -
kg m/s
It will be 62 over 72 so it is <span>0.861111111: Hope this helps</span>
The correct answer for this question would be the first option. In a neuromuscular synapse, it is the enzyme acetylcholinesterase, which is located at the motor end plate, that breaks down the neurotransmitter released from the axon. This <span>is responsible for stimulating terminating the stimulation of the skeletal muscle cell to make it contract. Hope this answer helps. </span>
