Answer:
When the metal wire in an incandescent lightbulb glows when the light is switched on and stops glowing when it is switched off, this is an example of resistance, which provides light and heat.
Explanation:
Answer:
P = 517.5 [kg*m/s]
Explanation:
We must remember that momentum is defined as the product of force by the time of force duration.

where:
P = momentum [kg*m/s]
F = force [N]
t = time [s]
![P=345*1.5\\P=517.5[kg*m/s]](https://tex.z-dn.net/?f=P%3D345%2A1.5%5C%5CP%3D517.5%5Bkg%2Am%2Fs%5D)
Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies.
Mathematically can be expressed as,

The upper frequency is 88Hz and the lower frequency is 6, therefore the Bandwidth would be,


The center frequency is given on the basis of the square root of the multiplication of the two reference frequencies, then,



Answer:
the force needed to give the truck the acceleration is 29,760 N.
Explanation:
Given;
mass of truck, m = 4800 kg
acceleration of the truck, a = 6.2 m/s²
The force needed to give the truck the acceleration is calculated as;
F = ma
F = 4800 x 6.2
F = 29,760 N
Therefore, the force needed to give the truck the acceleration is 29,760 N.
