2.Chemical energy is converted to mechanical energy.
3. Chemical energy is converted to heat energy.
4. Chemical energy is converted to mechanical and kinetic energy.
the correct answer is 1. Chemical energy is converted to mechanical and heat energy.
When the boy eats apple, the chemical energy of the apple first converted in the heat energy in the process of digestion, which maintains our body temperature, than the body of the boy converts the heat energy into mechanical energy.
Therefore the correct option is 1.
Answer:
Chemical energy is converted to mechanical and heat energy.
Explanation:
1000 centiliters = 1 liter.
500 centiliters = x liter
1000 / 500 = 1/x Cross multiply
1000x = 500 Divide by 1000
x = 500/1000
x = 1/2
500 centiliters = 1/2 or 0.5 of a liter.
For the conversion process, 500 centiliters is equivalent to 5 liters.
Centiliters (cL) and liters (L) are both units of volume. Centiliters are a smaller unit, while liters are a larger unit. To convert from centiliters to liters, use the conversion factor of 100 centiliters per 1 liter.
In the given scenario, there is 500 centiliters. To convert this to liters, divide the number of centiliters by 100. This division accounts for the fact that there are 100 centiliters in 1 liter.
Given:
500 centiliters (cL)
To convert 500 centiliters to liters:
500 cL รท 100 = 5 liters
Therefore, 500 centiliters is equivalent to 5 liters.

#SPJ6
As it is given that 2 kg mass is suspended by 12 cm long thread and then a horizontal force is applied on it so that it remains in equilibrium at 30 degree angle
So here we can use force balance in X and Y directions
now for X direction or horizontal direction we can use
for vertical direction similarly we can say
so here we first divide the two equations
now plug in all values in the above equation
Part b)
now in order to find the tension in the thread we can use any above equation
so tension in the thread will be 22.6 N
0.5mv^2 > 0.5*0.15*40*40=120J
24 meters per second
B.
60 milligrams
C.
15 liters
D.
6 joules
The correct answer to the question is D) 6 joules.
EXPLANATION:
As per the question, four measurements are given i.e 24 m/s, 60 mg, 15 L and 6 J.
We are asked to determine the measurement which corresponds to energy.
Energy is measured in various units like joule, erg, electron volt etc.
Joule is the unit of energy in S.I system.
Hence, the correct measurement which corresponds to energy is 6 joules.
All other measurements like 24 m/s, 60 mg and 15 L are not the measurements of energy. These are the measurements of speed, mass and volume respectively.
