A lemming running 3.22 m/s runs off a horizontal cliff. It lands in the water 7.54 m from the base of the cliff. How much time w

LekaFEV [45]

Answer: 2.34s

Explanation:

Given the following :

Horizontal Velocity(V) = 3.22m/s

Horizontal Distance = 7.54m

Therefore, the time spent in the air can be calculated thus:

Using the relation:

Speed = distance / time

3.22m/s = 7.54m / time

Time = 7.54m / 3.22m/s

Time = 2.34s

Jupiter is 318 times more massive than Earth. Based upon mass alone (i.e, if you were to place Jupiter at the same distance from

GuDViN [60]

Answer:

318 Earth-pull

Explanation:

Using Newton's law of gravitational force

F = GMm / r²

F is directly proportional to mass

let earth = m

then m .......... Earth-pull

318 m = 318 m × Earth-pull / m = 318 Earth-pull

What is the magnetic field strength, in units of microTesla (T), at a distance of 6.3 cm from a long straight wire carrying a cu

bezimeni [28]

Answer:

$2.1 \mu T$

Explanation:

The magnetic field strength is given by:

$B=\frac{\mu_0 I}{2 \pi r}$

where

$\mu_0$ is the vacuum permeability

I is the current

r is the distance from the wire

In this problem,

I = 6.5 A

r = 6.3 cm = 0.063 m

So, the magnetic field strength is

$B=\frac{(1.256\cdot 10^{-7} H/m)(6.5 A)}{2 \pi (0.063 m)}=2.1\cdot 10^{-6} T=2.1 \mu T$
