A. The work increases.
Work=Force*Distance
in this case, the force is the weight since we are moving in an upward direction.
Weight=Mass*Acceleration Due to Gravity
Since Gabriella is carrying a greater mass upward (herself and the two heavy books), her force upward is greater in the second case. Thus, since the distance is the same, the work done by Gabriella is also greater.
Due to the Law OF Conservation and The Law Of Momentum the force the mallet exerted is equal to the force exerted on the ball HOPE THIS HELPS
Answer:
True
Explanation:
It becomes a chain reaction
Answer:
Option B, by saltation in the first few meters above the land surface
Explanation:
In the process of saltation, sand is carried by air and the sand grains remains suspended for a small distance till the fall down. These sand grains form a parabolic trajectory before falling down. The other characteristics such as height and time of suspended grains depends on grain size, shape, and density, lift & drag force and characteristics of wind such as velocity and turbulence.
Hence, option B is correct
Answer:The difference between mass and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass. Mass is the measure of the amount of matter in a body. ... Weight usually is denoted by W. Weight is mass multiplied by the acceleration of gravity (g).
Explanation:
A simple weight definition for kids is: weight refers to the force gravity applies to an object. A simple mass definition for kids is: mass reflects the amount of matter (i.e., electrons, protons and neutrons) an object contains. We can place a scale on the moon and weigh an object there.
