<span> The Andromeda Milkyway is a galactic collision predicted to occur in 4 billion years. I believe thats the answer</span>
Answer:
Option b.
Explanation:
Weight of skydiver = mass × acceleration due to gravity
= 113 × 9.81 N
= 1108.53 N
Now,
The weight is acting downwards and air resistance is acting upwards. So,
Net force = weight - air resistance
Net force = 1108.53 - 660
Net force = 448.53
Closest value is option b.
Answer: F = 2.1 x 10^-4N
Explanation: Question is incomplete.
The complete question is; A straight, 2.5-m wire carries a typical household current of 1.5 A (in one direction) at a location where the earth’s magnetic field is 0.55 gauss from south to north. Find the magnitude and direction of the force that our planet’s magnetic field exerts on this wire if it is oriented so that the current in it is running (a) from west to east.
Given parameters; l = 2.5m, I = 1.5A, B = 0.55 guass = 0.55 x 10^-4 Tesla , theta = 90 (from West to East), F = ?
F = BILsin(theta)
F = 0.55 x 10^-4 x 1.5 x 2.5 x sin 90
F = 2.1 x 10^-4 N.
According to right hand rule, it's direction is upward.
d. lower frequencies and low energy.
Explanation:
Microwaves and infrared waves are lower frequencies and lower energy waves.
They are both non-ionizing radiation.
- Microwaves and infrared waves are both electromagnetic waves.
- They do not require a material medium to be propagated in nature.
- They have little energy because the have very low frequency.
- They also have very long wavelengths.
