Answer:
it would have run 498 miles
Explanation:
if the polar bear runs 8.3 every second then multiply 8.3 times sixty to get 498
There are very scarce food resources for the other animals and for the deers themselves which can cause massive death if all of the food is eaten
Answer:
The average force exerted by the person on the box is 20 N.
Explanation:
Given that,
Impulse applied to the box, m = 5 kg-m/s
Time of contact of the person with the box is 0.25 seconds. We need to find the average force exerted by the person on the box. The impulse applied on an object is given by :
F is the average force exerted by the person on the box
F = 20 N
So, the average force exerted by the person on the box is 20 N. Hence, this is the required solution.
The emf induced = B*l*v where B is the flux density, l the length of the conductor and v the velocity of the conductor. In the given case B = 0.035 N/amp.meter, l = 0.86 and v = 6 m/sec
emf = 0.035*0.86*6 = 0.1806 v ≈ 0.18 v
choice: D
Explanation:
Given parameters:
Force = 500N
Acceleration =
Unknown:
Weight can be used to this problem = ?
Solution:
Weight is the vertical force on a body;
Weight = mass x acceleration
So from this we can find the mass and then convert to the second wealth.
