a battery can provide a current of 3.80 a at 1.20 v for 2.00 hr. how much energy (in kj) is produced?

Answers

Answer 1

According to the question, the energy produced by the battery is 32.92 kJ.

What is energy?

Energy is the ability to do work. It is the capacity to move an object or to cause change. It can exist in different forms such as electrical, thermal, radiant, chemical, mechanical and nuclear. All of these forms of energy can be generated in various ways. They can be used to power machines, create light, heat water, generate electricity and power vehicles. Energy is also necessary for the body to live, think, move, and stay healthy.

Step 1: First, calculate the total charge produced by the battery

Charge (Q) = Current (I) x Time (t)

Q = 3.80 A x 2.00 hr

Q = 7.60 Ah

Step 2: Then, calculate the total energy produced by the battery

Energy (E) = Voltage (V) x Charge (Q)

E = 1.20 V x 7.60 Ah

E = 9.12 Wh

Step 3: Finally, convert the energy produced into kilojoules

1 Wh = 3600 kJ

E = 9.12 Wh x 3600 kJ

E = 32.92 kJ

Therefore, the energy produced by the battery is 32.92 kJ.

There is a scale with a basket on it. A brick, brick #1 is placed on the scale. The brick has a mass of 10 kg. What are the two forces acting on the brick?

Answers

Answer:

Weight and reaction.

Explanation:

With respect to Newton's third law of motion, action and reaction have equal magnitude but acts in opposite direction.

Thus, the brick of mass 10 kg has its weight (due to gravitational pull of the earth), which acts downwards through its center of mass. This makes the scale to produce an opposing force of equal magnitude, which acts upwards. These two forces acting in opposite directions balancing each other.

The two forces acting on the brick are: its weight and the reaction from the scale.

A wave hits an object as shown. A vertical line with Medium 1 to the left and Medium 2 to the right. An arrow from the left reaches the line. An arrow starts from the same point on the line and goes right at a different angle. Which kind of wave interaction is shown?

Answers

Answer:

refraction

Explanation:

When the wave moves from medium 1 to medium 2, then the wave gets refracted. Then the correct option is C.

What is the wave?

A wave is an energetic disturbance in a medium that doesn't include any net particle motion. Elastic deformation, a change in pressure, an electric or magnetic intensity, an electric potential, or a change in temperature are a few examples.

A wave is a dynamic disturbance of one or more variables that propagates in physics, geometry, and related sciences. When waves oscillate frequently around an equilibrium value at a certain frequency, they are said to be periodic.

The bending of waves as they go from one substance to another is known as wave refraction. It bends when the wave enters a new material because the wave's speed changes. The optical density or index of refraction of the material affects how light waves bend.

Thus, the correct option is C.

1. A stone is thrown upwards with an initial velocity of 25 m/s at angle of 30° to the ground a. Show that the vertical component if the velocity at the starting is 12.5 m/s upwards.

Answers

The vertical component of the velocity at the starting is 12.5 m/s upwards.

What is velocity?

Velocity is the direction at which an object is moving and serves as a measure of the rate at which its position is changing as seen from a specific point of view and as measured by a specific unit of time.

In kinematics, the area of classical mechanics that deals with the motion of bodies, velocity is a fundamental idea.

Given that  stone is thrown upwards with an initial velocity of 25 m/s at angle of 30°.

Hence,  the vertical component of the velocity in upward direction = 25 sin30° m/s

= 25 × 1/2 m/s

= 12.5 m/s.

2, A rectangular Container of base 50 cm by 30cm is filled with water to be depth of 5cm. how much is the pressure exerted at the base? (take pw= 1000kg /m3 and g=10m/s)​

Answer:

P = 500 N/m²

Explanation:

Pressure exerted at the base is the hydrostatic pressure and it is given by the formula;

P = ρgh

Where;

ρ is density = 1000 kg/m³

g = 10 m/s²

h is depth = 5 cm = 0.05 m

Thus;

P = 1000 × 10 × 0.05

how does a longshore current affect a beach?

Answers

Longshore currents are affected by the velocity and angle of a wave. When a wave breaks at a more acute (steep) angle on a beach, encounters a steeper beach slope, or is very high, longshore currents increase in velocity. ... This process, known as “longshore drift,” can cause significant beach erosion.
