What is the namefor the ratio of the
voltage applied to
a circuit and the
current in a circuit?

Answers

Answer 1
Answer:

Answer:

The relationship between voltage and current is called resistance. The relationship between all 3 is called Ohm's Law.

General Formulas and Concepts:
Circuits

Ohm's Law: V = IR

  • V is voltage/EMF
  • I is current
  • R is resistance

Explanation:

Ohm's Law is the fundamental basic for an ohmic surface. All circuits follow Ohm's Law if it is ohmic and assuming all other things constant. It tells the importance of the relationship between voltage, current, and resistance in a given current of a battery, wire, and resistor.

It is wise that you memorize this and understand the relationship between all 3.

two small balls are suspended on parallel threads of the same length so that they touch each other in the vertical position. the mass of the first ball is 0.4kg and the mass of the second ball is 200g. the first ball is deflected so that its centre of mass rises to a height of 6cm and it is then released. to what maximal height will the 200g ball rise if the collision is elastic?

Answers

Answer: 12cm

Explanation:

Since first ball is raised to a height h1= 6cm, it gains a potential energy(PE1). On release, this PE1 is converted to kinetic Energy (KE1). This KE1 impact it energy on ball 2 ans it rise also. Since collision is elastic.

KE1 = KE2 ....> PE1 = PE2

m1 ×g × h1 = m2 × g× h2

h2 = m1×h1/m2

h2 = 0.4 × 0.06/0.2

h2 = 0.12m = 12cm

Radiation transfers energy by moving matter. Please select the best answer from the choices provideda. True
b. False

Answers

The answer is b. False because radiation transfers energy by the propagation of waves within the electromagnetic spectrum and the travel of photons. Therefore, no matter is moved within this process.

False

Answers

Answer: 38.25 m

Explanation:

In this situation we need to find the distance d between the rabbit and the carrot, and we can use the following equation, since the rabbit's acceleration is constant:

V^(2)=V_(o)^(2) + 2ad(1)

Where:

V=13 m/s is the rabbit's maximum velocity (final velocity)

V_(o)=4 m/s is the rabbit's initial velocity

a=2 m/s^(2) is the rabbit's acceleration

d is the distance between the rabbit and the carrot

Isolating d:

d=(V^(2)-V_(o)^(2))/(2a)(2)

d=((13 m/s)^(2)-(4 m/s)^(2))/(2(2 m/s^(2)))(3)

Finally:

d=38.25 m
