C. The Densities are equal.
<h3>
What is density?</h3>
Density is mass per unit volume or mass of a unit volume of a material substance.
If m1, V1 and D1 = mass, volume and density respectively of ball C
m2, V2 and D2 = mass, volume and density respectively of ball D
According to the Question ,

Therefore,

Hence, D1 = D2

Answer:
the answer is 0 .75m
Explanation:
where are finding the distance the speed is given as well as the time..so you multiple the speed with the time thus you get the distance..i hope that's the answer..
a)You throw a stone horizontally at a speed of 5.0 m/s from the top of a cliff that is 78.4 m high.
from above statement we got
height = 78.4 m
since the ball is thrown, so its vertical velocity would be zero
u = 0
taking g = 9.8m/s^2
now, using the equation of motion
h = ut + gt^2/2
now putting all the values in it
we got ,
78.4 = 9.8 * t^2/ 2
by solving we got,
t = 4 sec
b) now, since along the horizontal , no force acting and accelaration is zero so
R = ut , R is RANGE
R = 5 * 4
range = 20 m
c) vertical components of the stone’s velocity just before it hits the ground = v sin θ =
horizontal components of the stone’s velocity just before it hits the ground = v cos θ

Answer:
Energia termica: La energía térmica es la forma de energía que interviene en los fenómenos caloríficos. Cuando dos cuerpos a diferentes temperaturas se ponen en contacto, el caliente comunica energía al frío; el tipo de energía que se cede de un cuerpo a otro como consecuencia de una diferencia de temperaturas es precisamente la energía térmica.
Calor:La cantidad de energía térmica que un cuerpo pierde o gana en contacto con otro a diferente temperatura recibe el nombre de calor. El calor constituye, por tanto, una medida de la energía térmica puesta en juego en los fenómenos caloríficos.
