The resistance would go down since you essentially have one less resistor

A ball that has a mass of 0.25 kg spins in a circle at the end of a 1.6 m rope. the ball moves at a tangential speed of 12.2 m/s

NARA [144]

The centripetal force acting on the ball will be 23.26 N.The direction of the centripetal force is always in the path of the center of the course.

<h3>What is centripetal force?</h3>

The force needed to move a body in a curved way is understood as centripetal force. This is a force that can be sensed from both the fixed frame and the spinning body's frame of concern.

The given data in the problem is;

m is the mass of A ball = 0.25 kg

r is the radius of circle= 1.6 m rope

v is the tangential speed = 12.2 m/s

$\rm F_C$ is the centripetal force acting on the ball

The centripetal force is found as;

$\rm F_C = \frac{mv^2}{r} \\\\ F_C = \frac{0.25 \times (12.2)^2}{1.6} \\\\ F_C=23.26\ N$

Hence the centripetal force acting on the ball will be 23.26 N.

Why does ice reflect more energy compared to water?

Stells [14]

Answer:

while ice is made by water again it melts and becomes water. water is colourless and odourless and has no taste but ice is only cold and hard. water is used for drinking and other things. but is for freshness and it never flows

Explanation:

so ice reflect more energy compared to water

Radio waves just like light waves can be reflected refracted and diffracted and polarized.

hoa [83]

Radio waves just like light waves can be reflected refracted and diffracted and polarized. The answer is True. These characteristics are the common phenomena for electromagnetic (EM) waves, and Radio Waves are electromagnetic Waves so much so that they obey reflection, refraction, and diffraction.

How are magnetic forces like electric forces? (4 points) Select one: a. They both have charges b. In both, opposites attract. c.

nlexa [21]

Lets take it down a notch and break it down:

Magnetic forces and electric forces are quite similar, lets take a look at the answers possible:

A. They both have charges

False, magnetic forces do not HAVE charges, but they have an EFFECT on moving charges (that are creating a magnetic field around them).

Why? Electrical forces have positive and negative charges while magnetic forces have a north and south POLE. These two are different forces, therefore magnetic forces do not HAVE charges.

B. In both, opposites attract

We all know opposite poles attract, like poles, don't attract (repelling force). This is true for the magnetic force, now, the electric force, two positively charged particles will exert a repulsive force on one another. DING DING. We have a winner. B is TRUE.

C. In both, opposites repel

False, we already know in electric and magnetic forces that opposites attract and similar charges/poles repel.

D. Neither have charges

False, this is a joke question right? Don't even look at this one!!!!!!!!!

Therefore, B, is the only true answer that describes how magnetic and electric forces are similar.

Have a nice day!
