Answer:
the spring constant is -89.2857 n/m
Explanation:
The computation of the spring constant is shown below:
As we know that
Force in newtons = Spring constant × amount of extension
F = -k × x
where
F = 25 N
And, x = 0.280m
So, the spring constant would 2
= 25N ÷ 0.280 m
= -89.2857 n/m
Hence the spring constant is -89.2857 n/m
Answer:
Minimum speed will be equal to 2.213 m/sec
Explanation:
We have given radius of the r = 2 m
Coefficient of friction
At minimum speed frictional force will be equal to centripetal force
So
So the minimum speed will be equal to 2.213 m/sec
Answer:
Gravitational force
Explanation:
gravity is what keeps us down on earth so we don`t float away into space and it is constant it does it 24/7 365 days a year and the remaining time earth continues to survive
Well, half-life is the radioactivity of an identified isotope that decreases by half of the actual value.
So, your answer would be C.
Answer:
The length would be 4.
Explanation:
For this problem, we are going to use the formula, v = lwh. We already have the volume, height, and width, so let's plug it in.
104 = (l)(2)(13)
Now, we have to isolate our variable, which is l. To do this, we multiply 2 and 13 to get 26, and then move it to the other side by dividing both sides by 26.
104/26 = l(26)/26
Then we get 4 = l, which is our answer.
