Answer:
A, B, and E
Explanation:
C and D are wrong;
Line graphs do not show the dependent variable on the x-axis.
Line graphs do have both an x-axis and a y-axis.
Answer:
9833333.33 years
Explanation:
Speed of the land = 6 cm/y = v
Convert the speed to km/y
1 km = 10000 m
⇒1 m = 1/10000 km
⇒1 m = 10⁻⁵ cm
So,
6 cm/y = 6×10⁻⁵ km/y
Distance the land will travel = 590 km = s
Time taken
∴ Time taken by the land to move 590 km is 9833333.33 years.
Power = (voltage) x (current)
350 watts = (120 volts) x (current)
350 watts / 120 volts = current
current = 2.917 Amperes continuously
Answer
a) Electron is moving toward right and brought to rest it means that force should be in opposite direction of motion electron.
We know F = qE here q = -e so, Force will be F = - eE.
Force on electron will be acting in opposite direction so, the electric field direction will be towards Right.
b) we know,
Force on electron = Electric force
m a = eE
using equation of motion
v² = u² + 2 a s
0 = (5.5 x 10⁵)² - 2 x a x 0.05
e = 1.6 x 10⁻¹⁹ C
mass of electron, m = 9.1.09 x 10⁻³¹ Kg
now,
E = 17.22 N/C
hence, strength of electric field is equal to E = 17.22 N/C
