Answer:
The work done by the electric force is = 
The potential of the starting point with respect to the end point is 
The magnitude of E 
Explanation:
Looking at this we can see that the work done by the electric force is equal to the kinetic energy this is because on the electric field is uniform and that the work done resulted in motion.
Mathematically
Where 
is the potential difference
q is the charge whose value i given as = 
W is the workdone whose value is obtained as =
Substituting
Mathematically
Where E is the electric field strength
d is the distanced moved and it is given as 6.00 cm = 0.06 m
Making E the subject of the formula
The tilt of Earth's axis hope this helps
Answer: 216.2 J
Explanation: The heat energy of copper is the expressed in Q=mc∆T. First make sure that the mass 0.0693 kg is converted into grams to cancel both units.
Q= 69.3 g x 390 J/g°C x 26 °C-18°C = 216.2J
Answer:
d) Forces are applied equally in all directions
Explanation:
Confining pressures are pressures imposed on a layer of soil by the weights of the layers on top of it. Confining pressures occur as a result of equal transmission of forces between the layers of a material (usually rock and soil).
It can also be described as an equal, all-sided pressure produced by overlying rocks in the crust of the earth. As the confining pressure increases, the critical elastic energy of the layers of the material transforms from linear to exponential.
According to the elastic conservation momentum
m1v1 + m2v2 = m1V1 +m2V2
v: velocity before collision, V after collision
<span>the magnitude of the final velocity of the red marble
</span>m1v1 + m2v2 = m1V1 +m2V2
V2 is the final velocity we must find
V2 = 1 / m2 ( m1v1 + m2v2 - m1V1)
= 1/1.2 (3.5x15 + 1.2x 3.5 - 3.5x 5.5)= 63.29 cm/s
