Answer:
Decease the mass
Increase the force applied
Explanation:
To increase the acceleration of the shopping cart, Brielle should reduce the load inside her cart.
According to Newton's second law of motion;
Force = mass x acceleration
Now, mass is indirectly proportional to the acceleration. The more the mass, the lower the acceleration a body will generate.
Lighter bodies moves with a faster acceleration.
In this case the force applied is constant.
If the force applied is also, increased the acceleration of the body will increase also.
The best reason for buckling of rail tracks on hot summer days is the thermal expansion or compressive forces acting on the rail tracks.
<u>Explanation:</u>
The rail tracks are composed of metals and they are rigidly connected with each other. If the materials used in construction of rail tracks are old, then there can be weakening of the track materials leading to decrease in their resistivity to thermal heat.
So this increase in temperature on hot days leads to compressive stress on the tracks which causes the tracks to expand and misaligned themselves.
Also the loosening of the ballast, ties and fasteners enhance the speed of buckling on hot summer days. Thus due to thermal expansion of the materials of the tracks, they buckle up as there is no space for desired expansion.
