Answer:
A
Explanation:
because she wants to practice science and A is the practical option.
Answer:

Explanation:
Take at look to the picture I attached you, using Kirchhoff's current law we get:

This is a separable first order differential equation, let's solve it step by step:
Express the equation this way:

integrate both sides, the left side will be integrated from an initial voltage v to a final voltage V, and the right side from an initial time 0 to a final time t:

Evaluating the integrals:

natural logarithm to both sides in order to isolate V:

Where the term RC is called time constant and is given by:

Displacement (s) of an object equals, velocity (u) times time (t), plus ½ times acceleration (a) times time squared (t2). Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth's gravitational force as the acceleration rate of an object.
Answer:
0.3 hours sooner than the normal time of arrival
Explanation:
Finding the difference in time of arrival of both speed will help know how much sooner.
Given:
Distance = 119 km
Speed 1 = 70 km/h
Speed 2 = 85 km/h
Time = Distance / Speed
For the time taken at the first speed
Time = 119/70
= 1.7 hours
For the time taken at the second speed
Time = 119/85
= 1.4 hours
∴ 1.7 hours - 1.4 hours
= 0.3 hours sooner
Answer:
11
Explanation:
There are 2.2lbs in a kilo
times the KG by 2.2 and u get the amount in lbs (pounds)
