Voyager 2 is a space probe, launched in 1977, to study the outer planets. It will continue to travel through space for thousands

of years without stopping. Which one of Newton's laws does this describe?
(I'm new to this website so Im just getting the hang of it)

physics A river flows at a speed vr = 5.37 km/hr with respect to the shoreline. A boat needs to go perpendicular to the shorelin

vova2212 [387]

Answer: Vb is the vector (-5.37m/s, 8.59 m/s), with a module 10.13m/s

then the ratio Vb/Vr = 10.13m/s/5.37m/s = 1.9

Explanation:

We can use the notation (x, y) where the river flows in the x-axis and the pier is on the y-axis.

We have Vr = (5.37m/s, 0m/s)

Now, if the boat wants to move only along the y-axis (perpendicularly to the shore).

The velocity of the boat Vb will be:

Vb = (-c*sin(32). c*cos(32))

Then we should have that:

5.37 m/s - c*sin(32) = 0

c = (5.37/sin(32))m/s = 10.13 m/s

the velocity in the y-axis is:

10.13m/s*cos(32) = 8.59 m/s

So Vb = (-5.37m/s, 8.59 m/s)

the ratio Vb/Vr = 10.13m/s/5.37m/s = 1.9 where i used Vb as the module of the boat's velocity.

Determine the value of the current in the solenoid so that the magnetic field at the center of the loop is zero tesla. Justify y

sleet_krkn [62]

Answer:

I will explain the concept of magnetic field and how it can be calculated.

Explanation:

The formula for magnetic field at the center of a loop is given as

B = μ $_{o}$ I / 2R

where B is the magnetic field

R is the radius of the loop

I is the current

and μ $_{o}$ is the magnetic permeability of free space which is a constant 4π × $10^{-7}$ newtons/ampere²

If the magnetic field at the center of the loop is 0, then μ $_{o}$ I = 0

I = 0 which means there will be no current flow in the loop.
