Answer:
6 and 8
Explanation:
The different positions of the moon, as seen from Earth, reflect how much light is being reflected off the moon from the sun.
Position 1 indicates the 3rd Quarter.
Position 2 indicates the Waning Gibbous.
Position 3 indicates the Full Moon.
Position 4 indicates the Waxing Gibbous.
Position 5 indicates the 1st Quarter.
Position 6 indicates the Waxing Crescent.
Position 7 indicates the New Moon.
Position 8 indicates the Waning Crescent.
You would read the diagram counterclockwise, with positions 7 to 3 as the moon increases light and positions 3 to 7 as the moon decreases light.
Therefore, we see that our 2 choices where we have a crescent is positions 6 and 8.
Answer:
61.76 N.
Explanation:
Given the mass of the car, m = 1.60 kg.
The speed of the car, v = 12.0 m/s.
The radius of the circle, r = 5 m.
As car is moving in circular motion, so net force ( normal force + weight of the car) is equal to centripetal force enables the car to reamins in circular path.
Let N is the normal force.
So, 

Now substitute the given values, we get


N = 61.76 N.
Thus, the magnitude ofthe normal force exerted on the car by the walls is 61.76 N.
B AND C I THINK I TOOK THIS ALREADY MS
Answer:
Part a)

Part b)

Part c)

Explanation:
Part a)
The height of the diving board is given as

now the speed of the diver is given as

when the diver will jump into the water then his displacement in vertical direction is same as that of height of diving board
So we will have



Part b)

plug in the values in the above equation


Part c)
Horizontal distance moved by the diver is given as



so the distance from the edge of the pool is given as
