Answer:
Oppenheimer suggested that the bomb laboratory operate secretly in an isolated area but allow free exchange of ideas among the scientists on the staff.
Explanation:
Answer:
Explanation:
a ) The sprinter at the very start of the race , pushes hard the ground under his feet in backward direction . The harder he presses the ground backwards , the greater reaction force he receives back in forward direction , throwing him forward direction. This force creates acceleration.
b ) The frictional force acting in opposite direction on the motion of ball creates - ve acceleration .
c ) The frictional force acting opposite to the motion of the ball creates - ve acceleration. The gravitational force acting on the ball in downward direction creates positive acceleration on the ball.
d ) The restoring force created in the bungee chord due to its extension creates acceleration in him in upward direction.
Answer:
a) The x coordinate of the third mass is -1.562 meters.
b) The y coordinate of the third mass is -0.944 meters.
Explanation:
The center of mass of a system of particles (), measured in meters, is defined by this weighted average:
(1)
Where:
- Mass of the i-th particle, measured in kilograms.
- Location of the i-th particle with respect to origin, measured in meters.
If we know that , , , , and , then the coordinates of the third particle are:
a) The x coordinate of the third mass is -1.562 meters.
b) The y coordinate of the third mass is -0.944 meters.
Answer:
By the principle of corona discharge.
Explanation:
The charge on each ball will decreases over time due to the electrical discharge in air.
According to the principle of corona discharge, when the curvature is small, the discharge of the charge takes placed form the pointed ends.
The answer to this question would be "d. all of the above", I believe. Thank you and I hope you have a wonderful day :)
