Answer:
B. ) 0.34 m
I definitely guessed and got the right answer so :))
Answer:

Explanation:
The density of an object is given by

where
m is the mass of the object
V is its volume
In this problem,
m = 42 kg
V = 22 m^3
Substituting into the equation, we find the object's density:

Answer:
Mass = 1350kg
Explanation:
Given the following data;
Velocity = 23m/s
Momentum = 31,050 kg·m/s.
To find the mass of car;
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
Momentum = mass * velocity
Substituting into the equation, we have
31,050 = mass*23
Mass = 31,050/23
Mass = 1350kg
Therefore, the mass of the car is 1350 kilograms.
Answer:
electric potential energy=

so the electric potential energy and distance(r) are inversely proportional.
then, the greatest energy occur in the smallest distance b/n the two balloon.
Answer:18 grams
Explanation:
The mass of an object doesn't change,it is the same everywhere irrespective of it location,therefore if the mass of an object in earth is 18 grams, the mass of the object in the moon will also be 18 grams
