Answer:
Density, d = 0.5 g/mL
Explanation:
It is given that,
Mass of the unknown liquid, m = 6 g
Volume of unknown liquid, V = 12 mL
Density is defined as the mass of the liquid divided by its volume. Mathematically, it is given by :
d = 0.5 g/mL
So, the density of the unknown liquid is 0.5 g/ml. Hence, this is the required solution.

Explanation:
The given data is as follows.
Spring constant (k) = 78 N/m,
Mass of block (m) = 0.50 kg
According to the formula of energy conservation,
mgh sin
h =
=
= 0.64 m
Thus, we can conclude that the distance traveled by the block is 0.64 m.
Answer : The correct option is, (C) 17 m/s
Explanation :
Formula used :
where,
K.E = kinetic energy = 6.8 J
m = mass of object = 46 g = 0.046 kg (1 kg = 1000 g)
v = velocity
Now put all the given values in the above formula, we get:
Therefore, the ball's velocity be as it leaves the cannon is, 17 m/s
