Answer:
A . pE=mgh 450kg*50m*10m/s^2=225000Joule
Explanation:
potential energy equals (mass) (gravity) (height)
Answer:
We all know that HCI is highly corrosive mineral acid. It's produced naturally in our (Human being) Stomach
It (HCI) is produced by the gastric glands in stomach. HCI activates the enzyme Pepsin and creates an acidic medium which kills the bacteria which might have entered while digestion & also making it simpler for further digestion.
HCI does not harm our stomach because the gastric gland also produces Mucus which helps in preventing the damage of inner wall (layer) of stomach from the action of this Acid.
D = 1/2gt^2 <-- free fall formula
d = (0.5)(9.81)(1.5^2)
d = 11.03625
d = 11.04 m
hope this helps and have a great day :)
The equation for calculating the Work is very simple that is Work=Force x Displacement. We have a Force given as 209N and displacement = 10 meter.
Putting these values directly in the formula gives us Work = 209N x 10m
Work = 2090 Joule.
The weight of the bricks is not needed hear.
R = ρ L/A. R= resistance, ρ= resistivity, L= length of the conductor. A = area of the conductor. Resistance is directly proportional to the length of the conductor. So if length of the conductor is decreased, resistance will also decrease. Hence A is the correct option
