Answer:
different temperatures
Explanation:
The independent variable would be <u>different temperatures</u>.
<u>The independent variable is the variable that is manipulated or varied in an experiment in order to see the effects it will produce on another variable</u> - the dependent variable. The values of the independent variable are directly inputted by the researcher and are not changed by any other variable throughout the experiment.
In the illustration, the effect of a variation in temperature is determined by counting the number of yeast cells. This showed that the manipulated variable is the temperature and hence, the independent variable.
Explanation:
The velocity of car A relative to car B is (10km/h+40km/h)=50km/h
From the calculation and the momentum of the body, the velocity is 62 m/s
<h3>What is momentum?</h3>
The term momentum refers to the product of mass and velocity. Now recall that the rate of change of momentum is equal to the impressed force.
Hence;
7440 kg-m/s = 120 kg * v
v= 7440 kg-m/s/120 kg
v = 62 m/s

Answer: None of the options
Explanation:
When we talk about uniform circular motion (constant speed) we yet have a changing velocity and therefore, acceleration.
How is this possible?
Well, velocity is a vector, and as a vector it has magnitude (the speed) and direction. So, while an object performs a uniform circular motion, althought its speed is not changing, its direction does change.
And, since acceleration
is the variation of velocity
in time
, certainly there is acceleration here.
![a=\frac{\Delta V}{\Delta t}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B%5CDelta%20V%7D%7B%5CDelta%20t%7D)
On the other hand, Inertia
is mathematically expressed as:
This means that for a system with a given axis of rotation and a given total mass
, the greater the distance from the axis
to the object that performs the circular motion, the greater the inertia.
This also means that inertia depends directly on the mass of the system and the radius of the circular motion, therefore, as long as these elements exist, in a circular motion the inertia will always be different from zero.
