Answer:
True
Explanation:
With the gravitational pull that our planets have, we are able to remain in orbit. This demonstrates how every object in the galaxy is attracted to every other object. Every object in the universe that has mass exerts a gravitational pull on every other mass. We as humans do it too, but since our force isn't strong, we don't have much of an effect.

Answer:
The strength of the magnetic field is 0.08 mT
Explanation:
Given:
Length of rod m
Velocity of rod
Induced emf V
According to the faraday's law
We know that the induced emf of rod is given by,
Where magnetic field
For finding the magnetic field,
mT
Therefore, the strength of the magnetic field is 0.08 mT
Answer:
Explanation:
According to Charles Law
=>
Where = 0.0279 m³, = 280 K and = 320 K
=>
=> = 0.03189 m³
Answer:
Z = 138.5 Ω
Explanation:
In a series RLC circuit the impedance is
Z =
the capacitive impedance is
X_C = 1 / wC
the inductive impedance is
X_L = wL
in this exercise indicate that C = 50 10⁻³ F, L = 0.3 H and the frequency is f=60 Hz
angular velocity and frequency are related
w = 2π f
w = 2π 60
w = 376.99 rad / s
let's calculate
Z =
Z =
Z = √19179.6
Z = 138.5 Ω
Use v^2 - u^2 = 2as
Here, u = 20 m/s , a = -0.5 m/s^2 and v = 0
- 400 = -s ======> s = 400 m
