Answer:
2500 kg/m³
Explanation:
The density is ...
(107 g)/((12.2 cm)(3.7 cm)(0.95 cm)) = 107/42.883 g/cm³ ≈ 2.5 g/cm³
In kg/m³, the density is ...
(2.5 g/cm³)×(1 kg/(1000 g))×(100 cm/m)³ = 2500 kg/m³
The conversion from CGS to MKS units of density is done using the usual method of units conversion. The conversion factor multipliers each change the units without changing the value, because their numerator is equal to the denominator.
__
2 significant figures are used because the block dimensions have a precision of 2 significant figures.
Answer:
the answer is 4 acceleration is 0
Explanation:
this is because when parallel line is drawn through x axis the velocity will bw uniform

Answer:
Explanation:
Given that:
thickness of the metal strip, 
width of the metal strip, 
magnitude of the perpendicular magnetic field, 
current through the strip, 
charge density, 
Hall voltage is a transverse voltage given by:
putting the respective values
Note:
V = E d is used when a charge is moved in a uniform electric field between the two oppositely charged plates, it can't be used here because it is the case of Hall effect where the small voltage develops transverse to the direction of current flow.
so 1/2mv^2
and the mass is 2 kg and the velociy is 25 so 1/2(2)(25)^2
which is 625 joules which is your answer
this is because the law of energy conservation states that energy can't be taken out of the system so assuming there is no friction the PE is the same as the KE
