Plz solve this question..

ivann1987 [24]

Answer:

Explanation:

Voltage = 12 (the two batteries are in series and the voltage adds).

Resistance = 3 ohms

I = V / R

I = 12/3

I = 4 amperes.

None of the answers are the right ones. If there is a fifth one that reads 4 amperes then it is the correct answer.

If you weigh 882 N on EARTH (HINT: What number do we ALWAYS use for gravity on Earth), what is your mass?

Softa [21]

882 divided by 9.81 (this is acceleration due to gravity) it equals 89.91

What’s Newton’s second law? Explain and mention some examples in daily life

Marina CMI [18]

Newton’s second law of motion is force equals mass times acceleration.

F = m•a

An example of this would be hitting a ball. If you hit the ball, it will move however fast you hit the ball. The harder you hit the ball, the faster it will move.

hope this helps and brainliest please

A conducting wire formed in the shape of a right triangle with base b = 25 cm and height h = 66 cm and having resistance R = 1.1

NemiM [27]

Answer:

$\omega=4.19 \,rad.s^{-1}$

Explanation:

To find:

angular frequency of rotation, ω=?

Given that:

base of wire triangle, b = 25 cm

height of wire triangle, h = 66 cm

electrical resistance , R = 1.1 Ω

time taken to make 1 rotation about the height through the base,T= 1.5s

magnetic field in +z direction out of the screen, B = 1.8 T

Since the wire does not carry any current therefore the magnetic field will have no impact on it.

Now, as we know:

angular frequency

$\omega= \frac{2\pi}{T}$

$\omega=4.19 \,rad.s^{-1}$
