Given value:
calculating the radiation absorbed per kg:
Answer:The higher up an object is the greater its gravitational potential energy. The larger the distance something falls through the greater the amount of GPE the object loses as it falls. As most of this GPE gets changed into kinetic energy, the higher up the object starts from the faster it will be falling when it hits the ground. So a change in gravitational potential energy depends on the height an object moves through.
Explanation: Lifting an apple up 1 metre is easier work than lifting an apple tree the same height. This is because a tree has more mass, so it needs to be given more gravitational potential energy to reach the same height.
R = 11 ohms
Explanation:
Given parameters:
Power of the electric toaster = 1100W
Voltage = 110V
Unknown:
Resistance, R of the heating coli = ?
Solution:
Electric power is given as:
Electric power = IV
where:
I is the current
V is the voltage
According to Ohm's law, V = IR
where R is the resistance. If we make current the subject of the formula and substitute, it gives:
Power = ![\frac{[tex]V^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Btex%5DV%5E%7B2%7D)
}{R}[/tex]
Power = ![\frac{[tex]110^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Btex%5D110%5E%7B2%7D)
}{R}[/tex]
R = ![\frac{Power }{[tex]110^{2}](https://tex.z-dn.net/?f=%5Cfrac%7BPower%20%7D%7B%5Btex%5D110%5E%7B2%7D)
}[/tex] = ![\frac{1100 }{[tex]110^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1100%20%7D%7B%5Btex%5D110%5E%7B2%7D)
}[/tex]
R = 11 ohms

I assume it is directed 30 degrees above the positive x-axis. F = 50 pounds F_x = 50 cos(30) pounds = 43.3 pounds F_y = 50 sin(30) = 25 pounds Let i and j be unit vectors along the x and y axes, respectively. Then F = F_x i + F_y j = (43.3 i + 25 j) pounds
