Calculate the momentum of a 1800 kg elephant charging a hunter at a speed of 7.50 m/s.
liq [111]

The amount of movement, linear momentum, momentum or momentum is a physical quantity derived from a vector type that describes the movement of a body in any mechanical theory. In classical mechanics, the amount of movement is defined as the product of body mass and its velocity at a given time.

p= mv

Where,

m = mass

v = Velocity

Our values are given as,

m = 1800kg

v = 7.5m/s

Replacing we have that,

p = (1800)(7.5)

p = 13500kg\cdot m/s

Therefore the momentum is 13500kg\cdot m/s

Derive the formula v= u+ at<br>please derive in detail ​
gogolik [260]

Lets do

We know

The rate of change of velocity is acceleration .

\\ \sf\longmapsto a=\dfrac{dv}{dt}

\\ \sf\longmapsto dv=adt

Integrate both sides

\\ \sf\longmapsto \int dv=a\int dt

As acceleration is constant .Take it outside of integral .On velocity we can take limit u to v and time from 0 to t

\\ \sf\longmapsto {\displaystyle{\int}}^v_u dv=a{\displaystyle{\int}}^t_0 dt

Hence

\\ \sf\longmapsto v{\huge{|}}^v_u=at

\\ \sf\longmapsto v-u=at

\\ \sf\longmapsto v=u+at

What variable did the researchers intentionally vary in the experiment
Dima020 [189]

Answer: Dependent Variable

Explanation:

There are two types of variable in any kind of experiment:

Independent Variable which are mostly known as inputs

Dependent Variables which are mostly known as outputs

In any experiment, the researches focus on observing the output values (dependent variables) by intentionally changing the inputs (Independent variables).

e.g. If we are observing the strain on any object, we try to change the value of stress on that particular object.

Here strain is a dependent variable whereas stress is an independent variable because it doesn't depend on whatever the value of strain may be.

When you mix two gases what can you predict about the conservation of volume in this case?
o-na [289]
Amagat's law of additive volumes states that we can simply add up the individual volumes of each gas (provided they are at the same temperature and pressure) to get the total volume of the mixture. Conservation of volume is an acceptable assumption for gases (but not always for liquid mixtures). This works for gases since the molecules are very small and only take up a minimal amount of space in a gas.
