Answer:
1020.4kg/m³
35m³
Explanation:
Given parameters:
Depth = 0.5m
Pressure exerted = 5000N/m²
Unknown = density of the liquid = ?
Solution:
To find the density of this unknown liquid, we use the expression below:
Pressure of liquid = density x height x acceleration due to gravity
5000 = density x 0.5 x 9.8
Density = 1020.4kg/m³
B.
Density of water = 1000kg/m³
Mass of water = 35000kg
Unknown:
Volume of water = ?
Solution:
The volume of water can be derived from the expression below:
Volume = 
Volume = 
= 35m³
B. 60 cm
All parallel light rays are bent through the focal point of a convex lens, so the rays from the flashlight 150 cm above the floor must go through the same point on the principal axis as the rays from the flashlight 120 cm above the floor. The location of the focal point does not change when the position of the object is moved either vertically or horizontally.
Hope this helps !
Answer:
The force exerted by X on Y is F to the right, and the force exerted by Yon X is F to the left.
Explanation:
There are two objects X and Y. Mass of object X is 2M, that is moving with a speed of 
and that of object Y is M that is moving with a speed of 
.
When both of the objects collide, the magnitude of the forces F the objects exert on each other is equal to :
The force exerted by X on Y is F to the right, and the force exerted by Yon X is F to the left using Newton's third law of motion. Hence, the correct option is (c).
Answer:
I think it is Velocity idk but does it hurt to try
