Answer:
v to the right.
Explanation:
<u>If there is no external force on the system, then the velocity of the center of mass is </u><u>constant</u><u>. </u>
The initial velocity of center of mass is v to the right. Therefore, the velocity of the center of mass at any point is v to the right.
<u>Answer</u>
C. 0.6125 m
<u>Explanation</u>
The magnification of an image produced by curved mirrors can be given in two ways;
Magnification, M = (Height of the image) / (height if the object) and
M = (image distance,V) / (Object distance, U).
Using the first formula,
M = 0.35/0.4
= 0.875
Now from the second formula,
M = V/U
0.875 = V/0.7
V = 0.875 × 0.7
= 0.6125 m
One form of Ohm's law says:
Voltage = (current) x (resistance).
= ( 9 A ) x (43 ohms)
= 387 volts.
Choice-A says this.
I would feel warm because putting cold and hot together is gonna be warm because with the cold it is cooling down the hot to make warm
