Answer:
The elevator must be moving upward.
Explanation:
During the motion of an elevator, the weight of the person deviates from his or her actual weight. This temporary weight during the motion is referred to as "Apparent Weight". So, when the elevator is moving downward, the apparent weight of the person becomes less than his or her actual weight.
On the other hand, for the upward motion of the elevator, the apparent weight of the person becomes more than the actual weight of that person.
Since the apparent weight (645 N) of the student, in this case, is greater than the actual weight (615 N) of the student.
<u>Therefore, the elevator must be moving upward.</u>
False. That's exactly how scientific theories begin
Answer:
The answer from this question is 3 m/s2.
Explanation:
8 m/s is initial velocity and 32 is final velocity. According to the rule of acceleration vf - vi we minus 8 from 32. Acceleration is the change of velocity per unit time. Then the difference (32 - 8= 24) is divided to 8. We get 3.
Answer:
162 N
Explanation:
Since the handbag weighs 162 N, from Newton's third law of motion, we know that to every action, there is an equal and opposite reaction. Thus, it means the force by each student arms Carrying the bag will be 162 N.
Since both handles of the bag are at same inclined angle of 60°, then the force in each students arm will be equal and thus;
F_each arm = 162 N
Silicon Dioxide is the answer
