Answer:
Explanation:
<u><em>Given:</em></u>
Weight = W = 600 N
Acceleration due to gravity = g = 3.7 m/s²
<u><em>Required:</em></u>
Mass = m = ?
<u><em>Formula:</em></u>
W = mg
<u><em>Solution:</em></u>
For m, it'll be
=> m = W/g
=> m = 600/3.7
=> m = 162.16 kg
Answer:
c. may be accompanied by the sound of explosively expanding hot air, called thunder.
Explanation:
Lightning is a discharge which is due to the reaction between oppositely charged charges in the clouds, or between clouds base and the Earth surface.
The motion of the cloud causes charging of clouds by friction, thus the reaction between opposite charges (jumping of charges from one cloud to another) in the cloud can lead to lightning. Also, oftentimes the bottom of a cloud is negatively charged so that this is attracted to the positive charge on the earth surface. Thus leading to a discharge called lightning.
Thus in the given question, the appropriate option is C. This implies that, lightning may be accompanied by the sound of explosively expanding hot air, called thunder.
Total distance = 10 km + 10 km = 20 km
1 km = 1000 m
20km x 1000 = 20,000 m
Total time = 20 min. + 30 min. = 50 minutes
Average speed = Distance / time
Average speed = 20,000/50 min
Average speed = 400 m/s
Answer:
A = 15 m/s , B = 18.75 m/s
Explanation:
from the velocity is equal to zero ( at rest ) , you see that velocity is increasing by 3.75 m/s for each second.
I hope that it's a correct answer.
