Answer: The weight of a 72.0 kg astronaut on the Moon is 117.36 N.
Explanation:
Mass of the astronaut on the moon , m= 72 kg
Acceleration due to gravity on moon,g = 1.63 
According to Newton second law of motion: F = ma
This will changes to = Weight = mass × g
The weight of a 72.0 kg astronaut on the Moon is 117.36 N.
Transverse waves is what its called
The correct answer is C.) a leaf
Answer:
A.) Time = 0.625 hrs = 37.5 minutes
B.) Speed required = 133.33km/hr
Explanation:
Given the following :
Total race distance = 100km
Total time required = 1 hour = 60 minutes
Average speed after traveling 50km = 80km/hr
80km/hr : This means it will take one hour to cover a distance of 80km
Therefore, time taken to cove first 50km at that average speed equals :
1 hour = 80 km
t hours = 50km
80t = 50
t = 50/80
t = 5/8 hours
t = 0.625hours
t = 0.625 * 60 = 37.5minutes
B)
Average speed required to complete the race in 1 hour = 100km/hr
Time used to complete first 50km = 0.625 hour
Time remaining: (1 - 0.625) hour = 0.375
Speed required = Distance left / time left
Speed required = 50 / 0.375
Speed required = 133.33km/hr
Answer:
Explanation:
<u>Accelerated Motion</u>
It occurs when an object changes its speed over time. If the changes in speed are uniform, then the acceleration is constant, positive if the speed increases, negative if the speed decreases.
The acceleration is calculated as follows:
The aeroplane starts with a speed of vo=62 m/s and reaches a speed of vf=6 m/s in t=35 s.
The acceleration is:
