A flashlight has a resistance of 2.4 what voltage is applied by the batteries if the current in the circuit is 2.5 a?

Answers

Answer 1
Answer:

Explanation :

The resistance of the flashlight is 2.4 ohms

The current flowing in the circuit is 2.5 A

The Ohm's law gives the relation between the following quantities i.e.

Current

voltage

and resistance

Mathematically, Ohm's law can be written as :

V =I R

V=2.5\ A* 2.4\ \Omega

V=6\ Volts

The voltage applied by the batteries is 6 volts.

Hence, this is the required solution.

An 89 kg person climbs up a uniform 13 kg ladder. The ladder is 5.9 m long; its lower end rests on a rough horizontal floor (static friction coefficient 0.26) while its upper end rests against a frictionless vertical wall. The angle between the ladder and the horizontal is 52◦. Let d denote the climbing person's distance from the bottom of the ladder (see the above diagram). When the person climbs too far (d > dmax), the ladder slips and falls down (kaboom!). Calculate the maximal distance dmax the person will reach before the ladder slips.

Two objects have mass 8 kg and 25 kg. Which one has more inertia?""

Answers

Answer:

the 25 kg one

Explanation:

The higher the weight the higher the inertia.
lets suppose we blow wind at both of these objects at a very high rate equally, u will notice after some time depending on the strength of wind the 8kg object will probably move earlier than the 25 kg one.

In which type of wave do the particles in a medium move perpendicular to the direction that the wave moves? A.transverse waves

B.ocean waves

C.surface waves

D.longitudinal waves

Answers

This type of wave is a transverse wave. Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.

What force is required to accelerate a body with a mass of 15 kilograms at a rate of 8 m/s²?

Answers

The equation for force is force is equal to mass times acceleration or F = ma where Force or F is measured in Newtons or N (which is also kilogram-meter per second squared), Mass or m is measured in kilograms or kg, and acceleration is measured in meters per second or m/s2. This leads to an answer in kilogram-meter per second squared or kg- m/s2, So if we multiply a body with a mass of 15 kilograms to a rate of 8 meters per second, we get 120 kilogram-meter per second squared. 
it is simple 120 N is the answer

A train traveling at 82.8 kilometers per hour is blowing its horn as it approaches you. The horn has a frequency of 312 Hz. Assume the speed of the sound is 331 m/s. What is the observed frequency of the horn?335 Hz
312 Hz
292 Hz
412 Hz

Answers

The answer is 335 Hz.

To calculate this, we will use the following formula:
f₀ = f × v ÷ (v - v₁)
where:
f₀ - frequency heard
f - actual frequency
v - speed of sound
v₁ - speed of source

We know:
f = 312 Hz
v = 331 m/s
v₁ = 82.8 km/h = 23 m/s

We need:
f₀ = ?

f₀ = f × v ÷ (v - v₁)
⇒ f₀ = 312 Hz x 331 m/s ÷ (331 m/s - 23 m/s)
⇒ f₀ = 312 Hz × 331 m/s ÷ 308 m/s
⇒ f₀ = 335.3 Hz ≈ 335 Hz

Thus, the frequency of the horn is 335 Hz.

335 Hz
