Meiosis is the correct answer because of the fact all the other answers are no where near correct
D. Gravity forced dust and gas together to form the planets and our earth
Answer:
a) 30.20 m/s
b) 12.91 m/s
Explanation:
Mass of squirrel = 575 g = m
Drag coefficient = 0.70 = C
Density of air = 1.21 kg/m³ = ρ
frontal surface area = 0.0146 m² = A
Height the squirrel falls = 8.5 m = h
a) Drag force
This force will oppose gravity
∴ Terminal velocity is 30.20 m/s
b) Neglecting drag force we get
∴ Velocity of a 56 kg person falling that distance, assuming no drag contribution is 12.91 m/s
Answer:
85 N
Explanation:
Given that crate mass = 20kg
Distance = 6m
Time = 3 seconds
Coefficient of kinetic friction = 0.3
We begin by calculating for acceleration
Which was gotten as 1.33 m/s sq

is the integrals for the magnitude of the electric field.
A characteristic of electricity exists at every location in space when charge of any kind is present. The value of E, often known as the electric field strength, electric field intensity, or just the electric field, expresses the strength and direction of the electric field.
The formula for the electric field due to a point charge is:
Here q is the charge, r is the distance from the charge, and k = 8.99 ×
Imagine an infinitely - tiny portion of this charge distribution that has a charge . This charge produces an electric field dE with magnitude:
Here, λ = 3.0 nC/m dq
= λ.dy dE = ∫k.dq
From y = -3 m to y = 2 m, there is a 3.0 nC/m uniform linear charge distributed along the y axis.
The integrals for the magnitude of the electric field at y = 4 m on the y axis:
