Your answer is C) The speed of sound is higher in solids than in liquids.
Answer:
The maximum velocity is 0.377 m/s
Explanation:
Please, the solution is in the Word file attached
The average speed is 116.66m/s.
Given - The path traced is 14km , time for jogging is 2 hrs=120min
To find the average speed-
- Speed refers to the ease of the movement and degree of mobility as a result of force application.
- Due to this there is involvement of velocity.
- Journey of average speed is the cumulative of distances and time.
- Kinetic theory refers to the Boltzmann constant connecting to the standards of distance traversed.
calculations-

Speed= 14 000 / 120
= 116.66m/s

Answer:
the charge per unit area on the plastic sheet is - 3.23 x 10⁻⁷ C/m²
Explanation:
given information:
styrofoam mass, m = 16 g = 0.016 kg
net charge, q = - 8.6 μC
to calculate the charge per unit area on the plastic sheet, we can use the following equation:

where
the force between the electric field
m = mass
g = gravitational force

where
q = charge
E = electric field
and
E = σ/2ε₀
where
ε₀ = permitivity
thus

mg = qσ/2ε₀
σ = (2mg ε₀)/q
= 2 (0.016) (9.8) (8.85 x 10⁻¹²)/( - 8.6 x 10⁻⁶)
= - 3.23 x 10⁻⁷ C/m²
<h2>Answer: Any new and abnormal growth</h2>
A <u>neoplasm</u> is any <u>uncontrolled growth</u> of abnormal cells or tissues in the body.
This abnormal mass can be benign or malignant (carcinogenic).
Therefore, the correct option is D.
