Answer:
1 × 10⁶ N/C
Explanation:
The magnitude of the electric field between the membrane = surface density / permittivity of free space = 10 ⁻⁵C/ m² / (8.85 × 10⁻¹²N⁻¹m⁻²C²) = 1.13 × 10⁶ N/C approx 1 × 10⁶ N/C
I think this answer Yes, salt is the crystal we use to season our food. But in chemistry, salt is a term used to describe a compound made by joining a positively charged acid with a negatively charged base. Table salt is the compound sodium chloride. It's composed of a positively charged sodium atom and a negatively charged chloride atom.
To calculate the acceleration of the truck, we use the equation of motion
Here, v is final velocity of the truck, u is initial velocity of truck, a is acceleration of the truck and t is time taken.
Given, u = 6 m/s, v = 14 m/s and t = 4 s.
Substituting these values in above equation, we get
.
Thus, the truck acceleration is 
Answer:
40.91 m/s
Explanation:
w = angular velocity of the ball about the elbow joint = 30.3 rad/s
r = radius of circular turn = distance of the ball from the elbow joint = 1.35 m
v = linear velocity of the ball
Linear velocity of the ball is given as
v = r w
Inserting the values given above in the equation
v = (1.35) (30.3)
v = 40.91 m/s
12.0 min = 720. s
so the distance covered moving at a constant 15.0 m/s is
(15.0 m/s) (720. s) = 10,800 m = 10.8 km = 1.08 × 10¹ km
