<h3>Answer;</h3>

Change in direction

Acceleration involves a change in speed and change in direction.

<h3>Explanation;</h3>

Acceleration is the rate of change in velocity. It is calculated by dividing velocity with time and measured in m/s².
Acceleration is a vector quantity, which means it has both magnitude and direction. Since direction is the rate at which velocity of a body or object in motion changes, it means it has two components direction and speed.
Therefore, acceleration is the increase in speed, or decrease in speed , or changing in direction.

Your toaster has a power cord with a resistance of 2.2x10^−2 Ω connected in series with a 9.7 Ω nichrome heating element. The po

kati45 [8]

Answer:

(A) 654.545 Kw

(B) $2.885\times 10^5kw$

Explanation:

We have given resistance of the toaster $R_1=2.2\times 10^{-2}ohm=0.022ohm$

Resistance of nichrome heating element $R_2=9.7ohm$

Both the resistances are connected in series so same current will flow through the circuit

Potential difference across the toaster V = 120 volt

So current $i=\frac{120}{0.022}=5454.5454A$

(a) Power dissipated in toaster $P=i^2R=5454.5454^2\times 0.022=654545.441W=654.545kw$

(B) Power dissipated in heating element $P=i^2R=5454.5454^2\times 9.7=2.885\times 10^8W=2.885\times 10^5kw$

When a charge is discharged to the earth, we call it?

Tems11 [23]

Answer:

lightning

Explanation:

correct answer is Lightning because it is the naturally occurring electrostatic discharge, during 2 electrically charge field in atmosphere and on the ground temporarily equalize themselves and they instantly release energy.
As it is released cloud so we called it lightning but a spark is generated when the electric field strength is sufficient to ionize the molecules of air, creating a small conduction path through the air.
This is usually a cascade process, because free electrons accelerate in the electric field and ionize more molecules by colliding.

Why are units of measurement useful?

Zanzabum

Without the ability to measure, it would be difficult for scientists to conduct experiments or form theories. Not only is measurement important in science and the chemical industry, it is also essential in farming, engineering, construction, manufacturing, commerce, and numerous other occupations and activities.
