Answer:

4.08 kg

Explanation:

We can apply the Newton's second law of motion to find the mass of this object:

$F=ma$ ,

where $m$ is mass, and $a$ is acceleration, which is substituted by $g$ here. Now, plugging given numbers in the equation, we have

$40=m\cdot9.8$ .

Solving for mass, we have

$m=\frac{40}{9.8}\\=4.08 \;\text{kg}.$

Static cling makes your clothes stick together. what causes this to happen? 1. external forces to the clothes 2. forces of natur

djyliett [7]

This phenomenon is as a result of static friction created by the tumbling clothes. Static friction results from the rubbing together of two or mores objects or body and electrons are stripped from one surface of the clothes more than the other. This creates an electrostatic force of attractions between the positive charges on one cloth and the negative charges on the other cloth.(unlike charges attract).

A charge +1.9 μC is placed at the center of the hollow spherical conductor with the inner radius 3.8 cm and outer radius 5.6 cm.

Archy [21]

To solve this problem we will apply the concepts related to load balancing. We will begin by defining what charges are acting inside and which charges are placed outside.

PART A)

The charge of the conducting shell is distributed only on its external surface. The point charge induces a negative charge on the inner surface of the conducting shell:

$Q_{int}=-Q1=-1.9*10^{-6} C$ . This is the total charge on the inner surface of the conducting shell.
