Yosef is playing with different kinds of rubber bands. Some are very narrow, and some are quite wide. Yosef is curious about the

rubber bands and develops this scientific question: Does the width of a rubber band affect how easily it can be stretched? He decides to develop a hypothesis to test this scientific question. What could Yosef’s hypothesis be?

Answer:

Yosef hypothesis could be stretching of rubber band depends on rubber band's width. It is difficult to stretch a wider rubber band in comparison to a narrow band.  

Explanation:

Width of rubber band affect how easily it can be stretched. It is found that it is difficult to to stretch a wider rubber band in comparison to a narrow band because when rubber band is narrow less molecules will be there along its width and hence less restoring force will be there so rubber can be easily stretched. On the other hand when the rubber band is wider it means more molecules  are there along its width and hence more restoring force will be there while stretching so it will be difficult to stretch a wider rubber band.

Answer:

If the width of a rubber band is increased, then it will be more difficult to stretch because more force will be needed to stretch it.

The solution for this problem:
The distance in mega parsec is equal to recession velocity / H, where h is equal to 50 mega parsec.The explanation for this is:1 parsec = 2.E+05 AU, nearly. 50 mega parsec = 1. E+13 AU, nearly. 1 mega means E+06 (million).

A vertical wall (8.7 m x 3.2 m) in a house faces due east. A uniform electric field has a magnitude of 210 N/C. This field is pa
Dominik [7]

Answer:

\phi=4344.72Nm^2/c

Explanation:

From the question we are told that:

Dimension of Wall:

 (L*B)=(8.7 m * 3.2 m)

Electric field B=210 N/C

Angle \theta =42 \textdegree North

Generally the equation for electric Flux is mathematically given by

 \phi=EAcos\theta

 \phi=210*(8.7*3.2)*cos 42

 \phi=4344.72Nm^2/c

What wave on the electromagnetic spectrum has the highest frequency?
Jet001 [13]

Answer:

Explanation:

Answer: Gamma rays

Gamma rays have the highest frequency.

What is an electromagnetic wave?

An electromagnetic wave requires no medium for its propagation.

It consists of a spectrum of different wavelengths.

Different wavelengths of rays have different energies and different frequencies.

Higher frequency rays have the highest energies.

What is gamma-ray?

These are ionized radiations.

Gamma radiations are obtained from the decay of the atomic nucleus.

It has the highest frequency which is why it can penetrate through matter.

It has the smallest wavelength and highest energy.

The frequency of gamma rays is more than 10^19 cycles per second and wavelength less than 100 picometers.

Briefly explain the factors that affect the center of gravity.
goldfiish [28.3K]

Answer:

:)

Explanation:

The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.

Can one individual represent and entire population? Why or why not
zubka84 [21]

Answer:

Explanation:

A representative does his/her utmost to convey the feelings of the majority of the group they speak for, and stands up for their interests. This might be for negotiation, voting, litigation, diplomacy, etc.  

A leader, ideally, inspires their constituents and brings out the best in them, as in strength, ethics, spirituality, and so on.  

Short version: a rep is an agent or conduit. A leader is a catalyst. Either job can be hard. And yes, it can be done for most of a population. Maybe not all, but not everyone can fit into the same mold.
