Answer:
0.368 cm
Explanation:
x = distance by which the mercury rise
d = depth of the water = 10 cm = 0.10 m
ρ = density of water = 1000 kgm⁻³
ρ' = density of mercury = 13600 kgm⁻³
P₀ = atmospheric pressure
Using equilibrium of pressure on both side
P₀ + ρ g d = P₀ + ρ' g (2x)
(1000) (0.10) = (13600) (2x)
x = 0.00368 m
x = 0.368 cm
Answer:
Explanation:
We can use the Einsten's relation which states the equivalence between mass and energy:
where
E is the energy
m is the rest mass of the object
c is the speed of light
By using this formula and m=2.5 kg, we can find the equivalent energy of the object:
The amount of gravitational pull an object experiences is its mass
<h3>
What is Weight ?</h3>
Weight can be define as gravitational pull an object. It is a product of mass and acceleration due to gravity. That is, W = mg. It is measured in Newton (N)
The amount of gravitational pull an object experiences is its mass and not density because the weight of an object depend on its mass and acceleration due to gravity.
W = mg
where
- g = acceleration due to gravity
Therefore, the amount of gravitational pull an object experiences is its mass

Answer:
Aim directly at the monkey
Explanation:
Despite the mass differences, both the monkey and the food will experience the same acceleration hence while the food follows a projectile path, it will then fall and hit the monkey hence achieving the aim of feeding it. You don't need to aim below or above, aim it directly.
Answer:
Black Flies, leeches and aquatic worms.
Explanation:
Black Flies, leeches and aquatic worms are the organisms that are tolerant to pollution and has the ability to survive in the polluted environment occur due to man-made waste. these organisms sometimes takes food from these pollutants and help in surviving these organisms. Without these tolerant organisms, those organisms which are not sensitive to these pollutants will die and removed from that polluted environment.
