The x and the y coordinates of the center of the mass of this system will be 43.1 m and 3.12 m respectively.
<h3>What is the center of mass?</h3>
A location is established in relation to an object or set of objects in the center of mass. It is the system's average position across all of its components.
Given data;
There are three little objects that are densely spaced out in the x-y plane.;
The value of the masses
m₁=1.41 kg
m₂=2.55 kg
m₃=3.19 kg
Hence, the x and the y coordinates of the center of the mass of this system will be 4.31 m and 3.12 m respectively.

Answer:
Explanation:
We have a metal ring of diameter
d = 4.2cm = 0.042m
r = d/2 = 0.021m
And it is place between the north pole and south pole of a large magnet with the plane of it's area perpendicular to the magnetic field.
Given that the magnetic field is
B = 1.12 T
The rate of decrease of magnetic field is 0.2T/s, since it is decrease then,
dB/dt = -0.2 T/s
The induce electric field is given as,
From faradays law
ε = ∫E•dl = -dΦ/dt
Magnetic flux is given as
Φ = BA
Φ = πr²×B = πr²B
Also, ∫E•dl = E×2πr = 2πrE
So,
∫E•dl = -dΦ/dt
2πrE = -d(πr²B) / dt
r is a constant, then
2πrE = -πr² dB/dt
Divide both side by πr
2E = -r dB/dt
E = -r dB/dt / 2
E = -0.021 × -0.2 / 2
E = 0.0021 V/m
The magnetic field point from north to south pole and it is decreasing and this means that the magnetic flux is also decreasing, so the induce magnetic field must point in the same direction of the original magnetic field, so the induce current circulate counter-clockwise as viewed from the south pole
Answer:
13.15 watt
Explanation:
work done = Force x displacement
W = 25.3 x 1.3
W= 32.89 J
Power = Work done / time
Power = 32.89 / 2.5
Power = 13.15 Watt
<em>GRAVITY !</em>
The object doesn't have to collide or even TOUCH something else in order to feel a gravitational force toward it.
If there's a gravitational force between the space object and ANYTHING else, (and there always is !), then that force will change the object's speed or direction of motion.
