Answer:
A. Scientists use seismic computer models to measure the atmospheric conditions above the Earth's crust
Explanation:
why would use atmosphere to study the layers of earth? dont think thats possible
Answer:
the rock hit the board you go flying because you board stops but you have energy still going so there for you go flying
Explanation:
Answer:
both mass take equal time to reach at bottom
Explanation:
As both masses M 1 and M 2 are situated at same height so that the potential energy at top is transformed to kinetic energy at the bottom by applying principle of energy conservation.
PE = KE
Mgh = (1/2)(M)(V^2)
V^2 = 2gh
V = (2gh)^(1/2)
So velocity is independent of mass
For M1
(M_1)(g)(h) = (1/2)(M1)(V^2)
V^2 = 2gh
V = (2gh)^(1/2)
For M2
(M_2)(g)(h) = (1/2)(M2)(V^2)
V^2 = 2gh
V = (2gh)^(1/2)
therefoer speed at bottom too are independent of mass
So we can say both speed are independent of therir respective mass
hence both take equal time to reach at bottom
Well you could drive stakes or piers down into the bedrock to anchor it, but you would still need to be cautious of erosion.
Answer:
Correct option is A)
Weight on earth = 600N
Let g= 10m/s2 on earth
Mass on earth = 10600=60 kg
Now, since mass is a constant quantity so, it will remain 60 kg on the moon also.
Now, weight on moon = mg′
m= mass =60 kg
g′ = acc. due to gravity on moon = 61th the value on earth
So, Weight on moon = 61th of the weight on earth
⇒ Weight on the moon =600×61=100 N
