Answer:
30 celsius
Explanation:
30 celsius = 86 fahrenheit
Anions: negatively charged atoms
Cations: positively charged atoms (CAT-ions are PAWS-itively charged)
Anode: positively charged electrode that allows electrical current flow (positive end of battery)
Cathode: negatively charged electrode that allows electrical current flow (negative end of batter)
The amount of power change if less work is done in more time"then the amount of power will decrease".
<u>Option: B</u>
<u>Explanation:</u>
The rate of performing any work or activity by transferring amount of energy per unit time is understood as power. The unit of power is watt
Here this equation showcase that power is directly proportional to the work but dependent upon time as time is inversely proportional to the power i.e as time increases power decreases and vice versa.
This can be understood from an instance, on moving a load up a flight of stairs, the similar amount of work is done, no matter how heavy but when the work is done in a shorter period of time more power is required.
Answer:
λ = 28,14 m
Explanation:
To find the wavelength of the wave you use the following formula:
(1)
v: speed of the wave = 1,97 m/s
λ: wavelength
f: frequency of the wave = 0,07 Hz
You replace the values of v and f in the equation (1) and solve for λ:

hence, the wavelength of the wave is 28,14 m
The force of the object with the given mass and acceleration is determined as 10 N.
<h3>
Force of the object</h3>
The force of the given object is calculated from Newton's second law of motion as follows;
F = ma
where;
- m is mass of the object = 5 kg
- a is acceleration of the object = 2 m/s²
F = 5 x 2 = 10 N
Thus, the force of the object with the given mass and acceleration is determined as 10 N.
The complete question is below:
Rearranging the equation m = F/a and solve for F, m= 5Kg and a= 2 m\s2
