A 4kg rock isn’t rolling 10m/s. Find it’s kinetic energy.

scoundrel [369]

Kinetic energy = (1/2) (mass) (speed)²

The rock's kinetic energy is not

(1/2) (4 kg) (10 m/s)²

= (1/2) (4 kg) (100 m²/s²)

= 200 Joules .

It may be more, or it may be less. The only thing
we can be sure of is that it is not 200 Joules.

A long, straight, horizontal wire carries a left-to-right current of 40 A. If the wire is placed in a uniform magnetic field of

sladkih [1.3K]

Answer:

The magnitude of the resultant of the magnetic field is $4.11\times10^{-5}\ T$

Explanation:

Given that,

Current = 40 A

Magnetic field $B=3.7\times10^{-5}\ T$

Distance = 22 cm

We need to calculate the magnetic field

Using formula of magnetic field

$B'=\dfrac{\mu_{0}I}{2\pi r}$

Where, r = distance

I = current

Put the value into the formula

$B'=\dfrac{4\pi\times10^{-7}\times20}{2\pi\times0.22}$

$B'=1.8\times10^{-5}\ T$

We need to calculate the magnitude of the resultant of the magnetic field

Using formula of resultant

$B''=\sqrt{B^2+B'^2}$

Put the value into the formula

$B''=\sqrt{(3.7\times10^{-5})^2+(1.8\times10^{-5})^2}$

$B''=4.11\times10^{-5}\ T$

Hence, The magnitude of the resultant of the magnetic field is $4.11\times10^{-5}\ T$

A man wishes to row the shortest possible distance from north to south across a river which is flowing at 2 km/hr from the east.

sweet-ann [11.9K]

From the diagram we have that

$sin\theta = \frac{2}{4}$

$\theta = sin^{-1} (\frac{1}{2})$

$\theta = 30\°$

Therefore the direction is 30° from east of south

What does g-force mean?

vekshin1

<span>Here, g is the acceleration due to gravity at the Earth's surface and is the standard gravity, defined as 9.8m/s....So, the force by that gravity is called g-force.....</span>
