Answer:
option (c)
Explanation:
90% of the body is submerged in water.
Now it is immersed in an unknown liquid whose density is less than the density of water.
Buoyant force acting on the body depends on the volume immersed, density of liquid and gravity.
As the density of liquid is less than the density of water, so the buoyant force acting on the body by the unknown liquid is less than water. So it is submerged less than 90% in this liquid.
Answer:
increase in temperature of water is 10° C
Explanation:
Given data
pizza = 500 kcal = 500000 calories
cold water = 50 L
to find out
increase in temperature of water
solution
we know heat formula that is
heat = m × specific heat × Δt
here m is mass = 50000 gram and Δt is change in temperature
and specific heat = 1 cal / gram C
so put here all value and find Δt
500000 = 50000 × 1 × Δt
Δt = 10° C
so increase in temperature of water is 10° C
Answer:
The Nucleus
Explanation:
Protons and Neutrons are found in the nucleus of an atom.
Explanation:
The given data is as follows.
Voltage = 2.50 V
Hence, calculate the equivalence capacitor as follows.
= 
C = 
Now, we will calculate the charge across each capacitance as follows.
Q = CV
= 
= 
= 
Thus, we can conclude that is the charge stored on each given capacitor.
