The strength of the electric field is 1.035 * 10^7 N/C.
<h3>What is the electric field?</h3>
The term electric field refers to the region in space where the influence of a charge is felt. Now we know that the electric field is obtained form the formula;
E = F/q
E = electric field
F = electric force
q = magnitude of charge
F = 8.8 * 10^-3 * 10 m/s^2 = 0.088 N
q = -8.5 nc or -8.5 * 10^-9 C
E = 0.088 N/ -8.5 * 10^-9 C
E = 1.035 * 10^7 N/C

Answer: 9.8N
Explanation: The velocity of a sound wave (v), tension on the string (T) and mass per unit length (u) are all related by the formulae below
T = v² * u
Where T is tension in Newton (N), v is velocity of sound waves in meter per seconds (m/s) and u is mass per unit length in kilogram per meter (kg/m)
u = mass of chord / length of chord
u = 0.44/ 8.1
u = 0.1 kg/m
Velocity of sound waves (v) =length of chord / time taken for wave to travel
v = 8.1 / 0.82 = 9.9m/s
Tension is calculated below using the formula
T = v² * u
T = (9.9)² x 0.1
T= 9.8N
Answer:
In our project, we have a class one lever that is hit by a pulley basket, thus letting a ball roll down.
Explanation:
Answer:
Zero
Explanation:
Momentum is the product of mass and velocity.
momentum = mv
For a system at rest, the velocity = 0
momentum = m*0
= 0
Even though the individual molecules in a system have some momentum, the system has no momentum because the system is at rest and is left standing.
