Answer:
3.6ft
Explanation:
Using= 2*π*sqrt(L/32)
To solve for L, first move 2*n over:
T/(2*π) = sqrt(L/32)
Next,eliminate the square root by squaring both sides
(T/(2*π))2 = L/32
or
T2/(4π2) = L/32
Lastly, multiply both sides by 32 to yield:
32T2/(4π2) = L
and simplify:
8T²/π²= L
Hence, L(T) = 8T²/π²
But T = 2.1
Pi= 3.14
8(2.1)²/3.14²
35.28/9.85
= 3.6feet
An consumer is an organism that gets energy from eating other organisms.
All animals are consumers
Answer:
The man will be able to move the crate.
Explanation:
= Coefficient of static friction between the crate and the floor = 0.2
= Coefficient of static friction between the man's shoes and the floor = 0.4
= Mass of crate = 150 kg
= Mass of man = 85 kg
g = Acceleration due to gravity = 9.81 m/s²
Horizontal force in order to move the crate is given by

Maximum force that the man can apply

Here it can be seen that
.
So, the man will be able to move the crate.
Answer:
The ball with the largest mass and highest specific heat capacity.
Explanation:
This is because, the thermal energy which is Q = mcΔT and since c = specific heat capacity of the ball, m = mass of ball and ΔT = temperature change = constant,
Q ∝ mc
So the thermal energy is directly proportional to mass and specific heat capacity of the ball, So, the ball with the highest product of these two properties has the highest thermal energy.
Answer:
D.
Explanation:
Force is strength and energy as an attribute of physical action or movement.
