Ingestion-and-Digestion-1

Easy

Question

A thin homogeneous rod of mass m and length $lambda$ is free to rotate in vertical plane about a horizontal axle pivoted at one end of the rod. A small ball of mass m and charge q is attached to the opposite end of this rod. The whole system is positioned in a constant horizontal electric field of magnitude $E equals fraction numerator m g over denominator 2 q end fraction$ The rod is released from shown position from rest.

What is the acceleration of the small ball at the instant of releasing the rod?

$\frac{8 g}{9}$
$\frac{3 g}{8}$
$\frac{7 g}{8}$
$\frac{8 g}{7}$

The correct answer is: $fraction numerator 3 g over denominator 8 end fraction$

Jasmine carried out an experiment. She placed two bowls of sand and water in the sunlight. She took the temperatures after an hour. She then took both the bowls into her home and placed them in an area with no light. She took another temperature after an hour and conducted the following observations:

Sand
Water

Before placing the bowls in the sunlight
37⁰C
30⁰C

After keeping the bowls in the sunlight for one hour
37⁰C
32⁰C

After keeping the bowl inside the house for one hour
31⁰C
31⁰C

How much does the temperature increase of the sand after an hour in the sun?
