Explanation:
The magnitude of a vector v can be found using Pythagorean's theorem.
||v|| = √(vₓ² + vᵧ²)
||v|| = √((-309)² + (187)²)
||v|| ≈ 361
You can find the angle of a vector using trigonometry.
tan θ = vᵧ / vₓ
tan θ = 187 / -309
θ ≈ 149° or θ ≈ 329°
vₓ is negative and vᵧ is positive, so θ must be in the second quadrant. Therefore, θ ≈ 149°.
Electrons are the right subatomic particle
Answer:
the 750 j will have potential energy is 375
Explanation:
750/2 is 375
Answer:
The minimum time to get the car under max. speed limit of 79 km/h is 2.11 seconds.
Explanation:

isolating "t" from this equation:

Where:
a=
(negative because is decelerating)

First we must convert velocity from km/h to m/s to be consistent with units.


So;

Satellites are objects which orbit the planet. The natural satellite of Earth, in this case, is moon
