Formulating a Hypothesis: Part I Since the investigative question has two variables, you need to focus on each one separately. T

hinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? Use the format of "if...then... because when writing your hypothesis

Answer:

If the mass of an object increases, then its kinetic energy will increase proportionally because mass and kinetic energy have a linear relationship when graphed.

Explanation:

Explanation:

The kinetic energy is said to be possessed due to the motion of the object. An object at rest will have zero kinetic energy and if it is in motion it will have some kinetic energy. The mathematical expression for kinetic energy is given by :

E=\dfrac{1}{2}\times m\times v^2...........(1)

Where

m is the mass of the object

v is the velocity of object

It is clear form expression (1) that the kinetic energy of the object is directly proportional to the mass and velocity of an object.

So, the hypothesis for the mass and kinetic energy can be written as " when the mass of the object increases, its kinetic energy also increases because there exists a direct relationship between the mass and the kinetic energy of the object".

A car is going 43m/s and travels 14 m, how<br> long did it take?
Burka [1]

Answer:

Time = 0.3256 sec

Explanation:

Velocity = displacement / time

43=14/t

So the time =14/43

t=0.3256 sec

The number of division on vernier scale is 20, Find the least count of the vernier calliper​
Anna35 [415]

Answer:

0.2 mm

Explanation:

Assuming the Caliper has 1 mm marks on the main scale. Again, we assume that the 20 division coincides with the 16 main scale division, then we can find the least count by saying

For the given Vernier calipers,

Let one main scale division be = 1 mm.

Since there are 20 Vernier scale divisions that happen to be equal to 16 Main Scale Divisions, we can calculate that

1 Vernier Scale Division = 16/20 Main Scale Division

1 Vernier Scale Division = 0.8 mm.

The least count is finally calculated by saying that

Least Count = 1 Main Scale Division - 1 Vernier Scale Division

Least Count = 1 - 0.8

Least Count = 0.2 mm

Therefore, from the assumptions made above, the least count is 0.2 mm

A long bar slides on two contact points and is in motion with velocity ν. A steady, uniform, magnetic field B is present. The in

Answer:

The induced current in the resistor is I = BLv/R

Explanation:

The induced emf ε in the long bar of length, L in a magnetic field of strength, B moving with a velocity, v is given by

ε = BLv.

Now, the current I in the resistor is given by

I = ε/R where ε = induced emf in circuit and R = resistance of resistor.

So, the current I = ε/R.

substituting the value of ε the induced emf, we have

I = ε/R

I = BLv/R

So, the induced current through the resistor is given by I = BLv/R
