1 gram per cubic centimeter is equal to 1000 kilograms per cubic meter. Just multiply it with a 1000 and you have your solution.
Answer: The coefficient of kinetic friction is μ = 0.6
Explanation:
For an object of mass M, the weight is:
W = M*g
where g is the gravitational acceleration: g = 9.8m/s^2
And the friction force between this object and the surface can be written as:
F = W*μ
where μ is the coefficient of friction (kinetic if the object is moving, and static if the object is not moving, usually the static coefficient is larger)
In this case, the weight is:
W = 20N
And the friction force is:
F = 12N
Replacing these values in the equation for the friction force we get:
12N = 20N*μ
(12N/20N) = μ = 0.6
The coefficient of kinetic friction is μ = 0.6
82ohms
Explanation:
The equivalent resistance in the circuit is 82ohms
Given parameters:
R1 = 50ohms
R2 = 32ohms
Unknown:
Equivalent resistance = ?
Solution:
A resistor is an body in circuit that opposes the flow of electric current.
Resistors are usually connected in circuit and in series arrangement.
When resistors are connected in series, they have the same current passing through them.
Equivalent resistance is the sum of each of the connected resistors
Equivalent resistance = R1 + R2 = 50 + 32 = 82ohms

Answer:
A
Explanation:
Because D is definitely true and there is only one false sentence what means if that non of B or C is false because if one is false so other one needs to be too.
