I think it's D. Usually, to find the volume of an irregularly shaped object, you put it in water with a labeled beaker to measure how much the water rises. The balance would be used to measure the mass in grams.

Answer:

option B

Explanation:

When a body is immersed in liquid there will be two force is acting on the body.

First one force acting downward due to weight of the body.

And the second force acting on the object will be buoyant force.

If the object is not in equilibrium the apparent weight will be equal to net force acting on the object.

$F_{net} = W - F_b$

W is the weight of the object acting downward

Fb is the buoyancy force acting upward on the object.

Hence, the correct answer is option B

If two lines in a system of linear equations have the same slope and same y-intercept, how many solutions will the system have?

arsen [322]

Answer:

We will have infinite solutions to the system of linear equations.

Explanation:

Well, when we have two lines with the same slopes and the same y-interception, both of them are overlapped, so we will have infinite solutions to the system of linear equations.

This kind of system is called dependent system.

I hope it helps you!

Need help with 4 &5 please help

DochEvi [55]

I can help you with 5. 5 is a displacement-time graph.
At A it is moving in a positive direction and speed is constant.
At B it is stationary or at rest.
At C, movement is negative and it is decreasing or decelerating
At D, it’s a general downwards movement in the negative direction that can be described as overall constant
