Answer:

Research bias or Experimenter bias

Explanation:

Research bias or Experimenter bias is the phenomena that results when the researcher's preferences or hopes about the result influences the obtained outcomes.

This can also be explained as a result of the unconscious  and subjective effect of the researcher's hopes on the data used in an experiment or the participants of the experiment or the outcome of the related experiment.

This can be avoided by the researcher by paying attention to the records made by the participants of the experiment and not based the outcome of the experiment on the basis of the his thinking.

4. A bullet of mass 30 g is fired from a rifle of mass 5kg at a speed of 259m/s. 
Ostrovityanka [42]

Answer:

Rifle Momentum=7.77kg*m/s v'= 1.554 m/s

Explanation:

a) m1v1 + m2v2 = m1v1' + m2v2'

0+0 = 0.03*259 + P(rifle momentum)

solve for P

p= 7.77kg*m/s

b) 7.77= 5*v'

v'= 1.554 m/s

What happens in terms of energy when a moving car hits a parked car, causing the parked car to move?
meriva
This is an example Newton's Third Law. All the kinectic energy from the moving car transferred the potential energy of the parked car. This potential is not much since the brakes are on (hopefully) and it's not in a non-moving position.

A uniformly charged, straight filament 6 m in length has a total positive charge of 3 µC. An uncharged cardboard cylinder 1 cm i
Lorico [155]

Answer:

Part A : 5.) = 564.704 N*m²/C

Part B:  10.) = 179751.0 V/m

Explanation:

A) Applying Gauss'Law to the straight filament, using a cylindrical gaussian surface with the filament as the central axis of the surface, assuming that the electric field is normal to the surface (which means that no flux exist through the lids of the cylinder) and is constant at any point of the surface (except the lids where is 0), we can find the electric flux, as follows:

E*2*\pi *r*l = \frac{Qenc}{\epsilon 0} (1)

where:

r is the radius of the cylinder = 0.05 m

l is the length of the cylinder = 0.01 m

Qenc, is the net charge on the filament enclosed by the gaussian surface

ε₀ = 8.8542*10⁻¹² C²/N*m²

In order to find the value of Qenc, we need to find first the linear charge density, as follows:

\lambda = \frac{Q}{L} =\frac{+3e-6C}{6m}  = 5e-7 C/m

The net charge enclosed by the gaussian surface will be just the product of the linear change density λ times the length of the gaussian surface:

Qenc = \lambda * l = 5e-7C/m * 0.01 m = 5e-9 C

According Gauss ' Law, the net flux through the gaussian surface must be equal to the charge enclosed by the surface, divided by the permittivity of free space (in vacuum or air), as follows:

Flux = \frac{Qenc}{\epsilon 0} = \frac{5e-9C}{8.8542e-12 C2/N*m2} = 564.704 (N*m2)/C

which is the same as the option 5.

B)  Repeating the equation (1) from above:

E*2*\pi *r*l = \frac{Qenc}{\epsilon 0} (1)

we can solve for E, as follows:

E =  \frac{Qenc}{2*\pi*r*l* \epsilon 0} = \frac{5e-9C}{2*\pi*(0.05m)*(0.01m)*8.8542e-12 C2/N*m2} = 179751.0 V/m

which is the same as the option 10 of part B.
