Answer:5 N
Explanation:
Given
A physics major is cooking breakfast when he notices that the frictional force between his steel spatula and his Teflon frying pan is only 0.200 N
And from tables of coefficient of Kinetic friction for Teflon is
and Friction force is
where N is the normal reaction
Answer:
+1/3
Explanation:
The lens equation states that:
where
f is the focal length
p is the distance of the object from the lens
q is the distance of the image from the lens
For a diverging lens, the focal length is negative:
and we also know that the object is placed a distance of twice the focal length, so
So we can find q from the equation above
And the magnification of the image is given by

Given that ,
To Find :
So , here use first equⁿ of motion which is ,
where ,
Now , substituting the respective values ,
Answer:
The mass is 12 kg
Explanation:
KE = mv²
Substitute:
600 = m(10)²
600 = m 100
600 = 50m
m =
m = 12
