Answer:
Cart A will bounce to the left while cart B will move right at less than 2 meters per second
Explanation:
Answer:
v = 2.89 m / s
Explanation:
This is a kinematics exercise, the centripetal acceleration is
a = v² / r
where a is the acceleration, v is the velocity and r the radius
let's clear
v = √a r
let's calculate
v = √ (27 0.31)
v = 2.89 m / s
this is the speed of the drum which is constant

Magnesium dichloride correct name for the ionic compound, MgCl2
Answer:
1/f = 1/o + 1 /i thin lens equation
1 / i = 1/f - 1/o = (o - f) / (o f) rearranging
or i = o f / (o - f) for the image distance
This image will be positive (real) with values given
m = -i / o magnification
m = - f / (o - f) shows m is negative and the image inverted
Also, since o here is large m will be small and the image is small
I think they mean A as the right answer
Different texts use different terms but here i is image distance and o the object distance
