Answer:
Two cars of equal weight and braking ability are travelling along the same road but combined with other factors it could mean the difference between life.
Answer:NO
Explanation:
No the mold should not be of the same size as that of sculpture because the material from which molds is made may shrink or expand depending upon its properties .
For example grey cast iron shrinks on cooling.
We need to make mold bigger in general so that if there is a need of finishing it can be done easily without altering the size of sculpture.
Responder:
43.84 m²
Explicación:
Dada la dimensión de una placa rectangular como:
Longitud (L) = 8.430 m
Ancho (W) = 5.201 m
El Área de una placa rectangular se puede obtener usando la fórmula:
Área = Largo × Ancho
Área = 8.430m * 5.201m
Superficie = 43.84443 m²
Área = 43.84 m²
Answer:
Explanation:
capacitance of sphere 2 will be 4.5 times sphere 1
a ) when spheres are in contact they will have same potential finally . So
V_1 / V_2 = 1
b )
Charge will be distributed in the ratio of their capacity
charge on sphere1 = q x 1 / ( 1 + 4.5 )
= q / 5.5
fraction = 1 / 5.5
c ) charge on sphere 2
= q x 4.5 / 5.5
fraction = 4.5 / 5.5
d ) surface charge density of sphere 1
= q /( 5.5 x A ) where A is surface area
surface charge density of sphere 2
= q x 4.5 /( 5.5 x 4.5² A ) where A is surface area
= q /( 5.5 x 4.5 A )
q_1/q_2 = 4.5
Answer: 27.21 V
Explanation:
The <u>electric potential</u> 
due to a point charge is expressed as:
Where:
is the <u>electric constant</u>
is the <u>electric charge of the hydrogen nucleus</u>, which is positive
is the <u>distance</u>
Rewritting the equation with the known values:
Finally:
