(3 m) / (2 mm/yr) = (3,000mm)/(2mm/yr) = 1,500 yrs.
This is the time required to age approx 75 generations of the best wine.
To answer this question we subtract the initial velocity from her final velocity. On the starting blocks the initial velocity was 0 m/s. Her final velocity was 11 m/s.t = 11m/s - 0 m/s, so the change in velocity is 11m/s. Time was 5 seconds.Plug it into the formula: 11 m/s ÷ 5 s= 2.2 m/s<span>2</span>
Radius of the circular loop is 0.0091m.
<h3>What is magnetic field?</h3>
Magnetic field is the area around a magnet where the magnetism influence is felt .
<h3>What is the magnetic field at the centre of a circular loop?</h3>
- The formula for magnetic field at the centre of a loop is
B =(μ)I/2r
- where B= Magnetic field at the centre of a circular loop
μ= Magnetic permeability =4(π)*10^(-7)
I= current flowing through the loop
r= radius of the loop
- Thus, radius of the loop =(4(π)×10^(-7)×5.7)/(2×3.9×10^(-4))
=0.0091m
Thus, we can conclude that the radius of the loop is 0.0091m .

#SPJ1
Answer:
Four times higher
Explanation:
F- G (m1 x m2)/ r^2
if r 1 = 2 and r 2 = 1 therefore F = G (m1 x m2)/ 1^2 is 4 times higher than
2^2 since G and m1 and m2 remained the same
