Answers
Answer:
Rubber or plastic covers are bad conductors of electricity. So they do not allow the electric current to pass through it.
Explanation:
Rubber and plastic are bad conductors of electricity, therefore when handling a tool with a rubber handle, the electricity will not pass through it.

rubber and plastic are insulators and are bad conductors of electricity
Imagine you are mpho:how can you help your friend (phenyo) not to be influenced by media? you really feel she needs some help because she is neglecting her school work write 2 paragraphs
Answers
One of the ways to help someone not to be influenced by media is:
Encourage independent thinking.Let her know that she should make sure the information she is consuming is free from bias and is factual.What is Media Influence?This refers to the effects and reactions which the mass media has on the people who listen to them by shaping their views and by controlling the narrative.
With this in mind, we can note that if a person is overtly influenced by the media, then such a person lacks independent thinking and becomes emotional by what he watches on the television or reads from an online source.
This can be changed through the encouragement of independent thinking, and the need to check for factual information from the media news and also to focus more on studies.

How does the sound of the recorder travel through the air?
Answers
Answer:
Every physical object causes vibrations when it moves in the air. This leads to creation of waves in the air that then continue to travel as a form of sound. Much like the drum example we've mentioned above, our vocal cords also vibrate when we talk. This vibration happens in air, solid mediums and liquid.

What is the electric potential 3. 0×10−11 m from a proton (charge +e )? Let V=0 at r=[infinity]
Answers
This question involves the concepts of electric potential, charge, and distance.
The electric potential is "48 V".
ELECTRIC POTENTIALThe electric potential of a point in the vicinity of a charge is given by the following formula:
[tex]V=\frac{kq}{r}[/tex]
where,
V = electric potential = ?k = Colomb's constant = 9 x 10⁹ N.m²/C²q = magnitude of charge = 1.6 x 10⁻¹⁹ Cr = distance from charge = 3 x 10⁻¹¹ mTherefore,
[tex]V = \frac{(9\ x\ 10^9\ Nm^2/C^2)(1.6\ x\ 10^{-19}\ C)}{3\ x\ 10^{-11}\ m}[/tex]

When someone hits a wooden board, what is the action force? What is the reaction force?
Answers
Answer:
The board did exert an equal and opposite force, but your mass is considerably greater than the mass of the board so all the friction between you and the ground keeps you from accelerating.
If you punched the board while standing on perfectly slippery ice, or in a vacuum, you would accelerate also, but at a much smaller rate than the board due to the mass difference.
If you could ignore all losses (friction, the board breaking, etc.) then all Newton's 3rd Law really is saying is that the center of mass of the system doesn't change when you punch the board. So the board accelerates in the direction of your punch and you move away from it at rates that keep the system center of mass constant.

What is the atomic bomb equivalent of energy released during a 7. 0 quake? an 8. 0 quake? a 9. 0 quake?
Answers
Answer:
7. 0 = 500 kilotons of TNT = 2.0 x 10^15 joules
8.0 = 15 million tons of TNT = 6.3 x 10^16 joules
9.0 = 500 million tons of TNT = 2.0 x 10^18 joules
atomic bomb dropped on Hiroshima had a equivalent of 15 kilotons TNT
Explanation:
formula :
log E = 5.24 + 1.5M
M is richter scale magnitude
if 8.3 = richter scale magnitude
log E = 11.8 + 1.5M Write the formula.
log E = 11.8 + 1.5(8.3) Replace M with 8.3.
log E = 24.25 Simplify
10^log E = 10^24.25
E = 10^24.25
E ≈ 1.78 x 10^24 ergs ≈ 1.78 × 1017 joules

92.BIO In an emergency situation,
a person with a broken forearm
ties a strap from his hand to clip
on his shoulder as in Figure P8.92.
His 1.60-kg forearm remains in a
horizontal position and the strap
makes an angle of 0 = 50.0° with
the horizontal. Assume the fore-
arm is uniform, has a length of
l = 0.320 m, assume the biceps
muscle is relaxed, and ignore the
mass and length of the hand. Find
(a) the tension in the strap and
(b) the components of the reac-
tion force exerted by the humerus
on the forearm.
Answers
Based on the principle of equilibrium of forces:
the tension T, in the strap is 10.2 Nthehorizontal component of the reaction, Rx is 6.56 Nthevertical component of the reactionary force, Ry is 7.84 NWhat is tension?Tension is a type of force that is transmitted through a flexible medium such as a cable, wire or string pulled tight by forces acting from opposite ends.
The tension in the strap is calculated as follows:
Taking sum of moments from the right end as equal to zero:
mg × l/2 = Tsinθ × l
T = mg/2sinθ
T = 1.60 × 9.8 / 2 sin 50°
T = 10.2 N
Calculating the components of the reac-
reac-tionary force:
Horizontal component is RxVertical component is RyFrom Newton's third law:
Rx = Tcosθ
Rx = 10.2 × cos 50°
Rx = 6.56 N
Ry - Tsinθ = 0
Ry = Tsinθ
where;
T = mg/2sinθ
Ry = mgsinθ/2sinθ
Ry = mg/2
Ry = 7.84 N
