Period is T = 1/f. The frequency, f, is 5cycles/10s = 0.5. So the period T=1/0.2 = 2.
The net horizontal force acting on the cart is 169.85 N.
The change in the carts momentum is 5,000 Ns.
The net horizontal force on Zanele is same as the net horizontal force on the cart.
If angle between the 500N force and the horizontal is decreased, the final velocity of the cart increases.
The given parameters:
- Mass of zanele, m1 = 40 kg
- Mass of the cart, m2 = 20 kg
- Applied force, F = 500 N, at angle 20 degrees
- Frictional force on the cart, Ff = 300 N
- Time, t = 10 s
<h3>Net horizontal force on the cart;</h3>
- The net horizontal force acting on the cart is calculated as follows;

<h3>Change in momentum;</h3>
- The change in the carts momentum at the given time of applied force is calculated as follows;

The net horizontal force on Zanele is same as the net horizontal force on the cart.
<h3>The final velocity of the cart;</h3>
- When the angle decreases the cart's final velocity would be affected as follows;

Thus, if angle between the 500N force and the horizontal is decreased, the final velocity of the cart increases.

Graphs because it has a lot of squares and it accelerates to 35 km/h in 20 seconds
Answer: Parietal
Explanation: The parietal lobe is where the primary somatosensory cortex is located. This cortex is where all tactile stimulation is processed in the brain and allows to you detect/feel someone scratching your back.
<span>Water is never added to earth system. Water forever remains in the water cycle on earth, so it goes from the ground, to the air, to the rain, to the sea, and round and round continuously. This cycle means that there does not need to be new water added to the earth, because it recycles any water that already exists of its own accord.</span>
