The kinetic energy of the tomato is :
K.E = 1/2 mv^2
K.E = 1/2 x 0.18 kg x 11 m/S^2
K.E = 0.99
Hope this helps
It’s coming in contact with more air molecules than I would if it was in a ball because there is less surface area
Explanation:
Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s)
which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it's running.
Answer:
12 A
Explanation:
Given,
Power of electric kettle=2.2 kW=2200W (since 1kW=1000W)
Voltage=180V
Current=?
Power = Voltage*Current
Current = Power ÷ Voltage
=2200W ÷ 180V
=12.22 Ampere
=12 A
A scientific journal article that is peer reviewed. This is because it is more likely not have factual information and sources to that information.
