: In general, metals feel colder or hotter to the touch than other materials at the same temperature because they're good thermal conductors. This means they easily transfer heat to colder objects or absorb heat from warmer objects
Answer:
Could it be Bond together?
Explanation:
Usually the word bond means join I may be wrong sorry x
Answer:
A) False
B) False
C) True
D) False
Explanation:
A) False, because when leaving the field, the coil experiences a magnetic force to the right.
B) When the loop is entering the field, the magnetic flux through it will increase. Thus, induced magnetic field will try to decrease the magnetic flux i.e. the induced magnetic field will be opposite to the applied magnetic field. The applied magnetic field is into the plane of figure and thus the induced magnetic field is out of the plane of figure. Due to that reason, the current would be counterclockwise. So the statement is false.
C) When the loop is leaving the field, the magnetic flux through the loop will decrease. Thus, induced magnetic field will try to increase the magnetic flux i.e. the inducued magnetic field will be in the same direction as the applied magnetic field. The applied magnetic field is into the plane of figure and thus the induced magnetic field is also into the plane of figure. Due to that reason, the current would be clockwise. So the statement is true.
D) False because when entering the field magnetic force will be toward left side
Answer:
The smaller ball (the tennis ball) will receive a much larger acceleration than the soccer ball of larger mass.
Explanation:
According to Newton's 2nd Law of motion,
(force equals mass times the acceleration imparted)
Since in this case we have the same force (50 N) applied to two different masses (one the tennis ball "m" which has smaller mass than the soccer ball of mass "M"), then the resultant accelerations will be different being the acceleration of the tennis ball (
) much larger than the acceleration imparted to the soccer ball (
), as can be seen from solving for the acceleration in the previous equation:
![F=mass*a\\a=\frac{F}{mass} \\a_t=\frac{F}{m} =\frac{10N}{m} \\a_s=\frac{F}{M} =\frac{10N}{M}](https://tex.z-dn.net/?f=F%3Dmass%2Aa%5C%5Ca%3D%5Cfrac%7BF%7D%7Bmass%7D%20%5C%5Ca_t%3D%5Cfrac%7BF%7D%7Bm%7D%20%3D%5Cfrac%7B10N%7D%7Bm%7D%20%5C%5Ca_s%3D%5Cfrac%7BF%7D%7BM%7D%20%3D%5Cfrac%7B10N%7D%7BM%7D)
Notice than when calculating the acceleration of the tennis ball (
), we divide 10N by a smaller number (m), than when we calculate the acceleration of the soccer ball (
), when we divide by a large number (M) resulting in a smaller quotient.
