Answer:
Electric force, 
Explanation:
It is given that,
Charge on an electron is 
Electric field, 
We need to find the magnitude of the electric force on this electron due to this field. The electric force is given by :
So, the electric force is 
.
Answer:
776.6 w
1.04 hp
Explanation:
given:
Mass, m = 190kg
height change, h = 25m
time elapsed, t = 60 s
acceleration due to gravity, g = 9.81 m/s²
Potential energy required raising 190 kg of water to a height of 25m
= mgh
= 190 x 9.81 x 25
= 46,597.5 J
Power required in 60 s
= Energy required ÷ time elapsed
= 46,597.5 ÷ 60
= 776.6 Watts (Use conversion 1 W = 0.00134102 hp)
= 776.6 w x 0.00134102 hp/w
= 1.04 hp

The Si units of all the left measurements are true thus, in length the typical
and standard SI unit is meter. SI units, also called as International Standard
of Units, is composed of the following systematized units of physical measure
which include, mole (amount of substance), candela (luminous intensity), kelvin
(temperature), ampere (electric current), second (time), kilogram (mass), and meter
(length). Hence, these measures spheres in multiplication or division by power
of 10, increase or decrease in measure.</span></span>
The time for the car to drive directly south is determined as 7.15 s.
<h3>Time for the car to drive directly west</h3>
The time for the car to drive directly south is determined by applying the concept of slope.
slope = Δy/Δx
a = Δv/Δt
Δt = Δv/a
Δt = (26.8)/(3.75)
Δt = 7.15 s
Thus, the time for the car to drive directly south is determined as 7.15 s.

Answer:
That the Sun was the center of the universe.
Explanation:
Ptolemy believed in geocentrism, which means that the Earth is the center of the Universe. This was also supported by Aristotle. Copernicus on the other hand believed in a heliocentric system, which proposes that the sun is the center of the universe.
