➷ After 10,000 years the mass will be:
1,000 / 2 = 500
After 20,000 years the mass will be:
500/2 = 250
As you can see, the correct answer would be A. 20,000 years

Answer:
a)r' = 4 r
b)
Explanation:
Given that car is moving with uniform speed.
At the verge of sliding
Friction force = Force due to circular motion
So we can say that
-----1
Where is the coefficient of friction
r is the radius of circular path
V is the velocity of car
a)
if the car speed become double
It means that new speed of car =2V
lets tale new radius of circular path is r'
---------2
From equation 12 and 2 we cay that
r' = 4 r
It means that we have to increase radius 4 times to avoid sliding
b)
In the above expression there is no any terms of mass ,it means that sliding speed does not depends on the weight of car.
So the sliding speed will remain same.
Answer:
1.20372
Explanation: start with 39 times 2 for how much grams each day and then multiply that by 7 then the convert grams into pounds
hey there! the correct answer would be ozone! hope this helps!!
Answer:
Considering the lack of information, this is the best I can do.
The average velocity can be calculated via .
If there is acceleration instead of V or V not given, use the first kinematic equation:
Hope it helps :) and provide more complete information and I can answer better
