Answer:

1. Independent variable : pendulum's height

2. Dependent variable : Pendulum speed

Explanation:

In an experiment scientist uses such things to search for any cause and its effect. experimenters design the model in such a way that change in one of the item causes a change in another.

These are called variables which are independent variable and dependent variable. Independent variables can be changed by the experimenter while dependent variables are not controllable by the experimenter.

In the context, the hypothesis is when the pendulum's height is reduced, the clock will speed up.

1. Independent variable : height of the pendulum

2. Dependent variable : Pendulum speed

The density of benzene at 15 ∘C∘C is 0.8787 g/mL. Calculate the mass of 0.1700 LL of benzene at this temperature. Express your a
SVETLANKA909090 [29]

Answer:

Mass of benzene is: 149.3 g

Explanation:

Let's use density to calculate mass.

Density = Mass / Volume

Mass = Density . volume

Be careful, because density is in g/mL and the volume is in L. So let's convert the L to mL: 0.170 L . 1000 mL / 1L = 170 mL

0.8787 g/mL . 170 mL = Mass of benzene

Mass of benzene is: 149.3 g
