The magnitude of the electric field between the two electrodes in ionization type detectors is an electric field can be given in volts per meter.

The magnitude of the electric field varies with distance, d, from the charge based on the charge of the respective particle. Therefore, the electric field for a single point charge can be easily calculated from these measured values.

In the International System of Units, the electric field strength is measured in volts per meter (V/m).

Combustion is when you use oxygen to convert fuel to heat and light energy. Option B is correct.

Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives heat.

The fuel can be a solid, liquid, or gas.

For example, charcoal is combined with oxygen.

Combustion is commonly called burning, and the substance that burns is usually referred as fuel.

For combustion to occur few things must be present:

fuel to be burned.

A source of oxygen

A source of heat.

Hence, Combustion is when you use oxygen to convert fuel to heat and light energy. Option B is correct.

The car’s acceleration in g’s is equal to 0.67 m/s² and the centripetal force acting on is equal to 4033.47 Newton.

Since the car’s acceleration is given as 6.61 m/s², we would simply divide it by the acceleration due to gravity (9.8 m/s²) to calculate the car’s acceleration in g’s as follows:

Acceleration, g = 6.61/9.8

Acceleration, g = 0.67 m/s².

Mathematically, the centripetal force acting on this car can be calculated by using this formula:

Fc = mv²/r

Fc = (610 × 54²)/441

Fc = 1778760/441

Fc = 4033.47 Newton.

The claim of the student is True, he can produce linear momentum in carrom with the help of b.

To explain the principle of linear momentum we can say that:-

According to the principle of conservation of momentum, if two things collide, the total momentum before and after the impact will be the same if no external force occurs on the colliding items.

Linear momentum conservation When the net external force is zero, the momentum of the system remains constant, as expressed mathematically by the expression.

Initial momentum = final momentum

Formula of Linear momentum is:-

Linear momentum = mass × linear velocity

P = M × V

The law of momentum conservation is based on Newton's third rule of motion, which states every force has a corresponding and opposing reciprocating force.

So we understand that Principle of Linear momentum. The initial momentum is equal to final momentum after collision hence, the carrom striker follows the concept of linear momentum.

Answer:

Motion of an object that travels in a curved path under the influence of Earth's gravitational field. Examples include throwing a ball, javelin throw, and golf ball.

Explanation:

Answer:

1. In sports.

2. In programming or Animation.

3. In home appliances.

4. In military.

Explanation:

1. In sports. Being common in sports, projectile motion is applied in motion of a projectile which is usually a ball. This is because we are able to calculate the angle of the flight developed by a ball to maximize its distance or velocity. For example in baseball and basketball.

2. In programming or Animation. Considering that there is a challenge for animators and programmers in modern world, physics is applied in televisions or video games. For example a baseball being hit by a player in video game or TV, it should look real. Hence the application of projectile motion.

3. In home appliances. Appliances for example hose or water gun uses an application of projectile motion. As the water exits the hose or water gun, the angle over which the water travels depends on the distance moved and force that is being applied.

4. In military. Bullets being shot from the barrel of the gun is a projectile in air. The speed of the bullet is higher than that of the water exiting the hose therefore it will travel a longer distance. The manufacturers of weapons such as a gun tries to maximize the speed while minimizing gun's recoil.

The North America will not be able to view the eclipse because of its location on the earth caused by the tilting of the earth.

The tilt of the Earth is what causes seasons to occur. These are the seasons in relation to the Northern Hemisphere.

The tilting of the Earth causes the difference in the amount of sun reaching each region of the earth like in the North America continent.

The potential energy of the bowling ball due to its position above the ground is 137.2 Joules. Therefore, the correct answer is 137 J The correct option is (b).

Given:

mass (m) = 7.00 kg

gravitational acceleration (g) = 9.80 m/s²

height (h) = 2.00 m

The potential energy of the bowling ball due to its position above the ground, we can use the formula for gravitational potential energy:

Potential Energy (PE) = mass × gravitational acceleration × height

The potential energy:

PE = 7.00  × 9.80 × 2.00 m

PE = 137.2 Joules

So, the potential energy of the bowling ball due to its position above the ground is 137.2 Joules. Therefore, the correct answer is 137 J (b).

Explanation:

Deep sea and sea floor marine habitats would have the least access to primary producers. The correct option is (d).

Primary producers would have the least access to habitats in the deep sea and on the ocean floor. Primary producers are animals and plants that can use sunlight as an energy source to photosynthesize and make their own food, including algae and phytoplankton.

Because of the depth of the water, light penetration is constrained in the deep sea and sea floor settings, making it difficult for creatures that rely on photosynthesis to survive.

In comparison to other maritime ecosystems, where sunlight is more easily obtainable, such as coral reefs, lagoons, salt marshes, estuaries, mangroves, and intertidal zones, these habitats often have lower amounts of primary production.

Yes

Explanation:

Average velocity is the ratio of total displacement and time taken for that displacement:

[tex]average \space\ velocity = \frac{displacement}{time}[/tex]

This means if displacement is zero, then average velocity will also be zero.

Displacement is zero when an object moves some distance in one direction, and then moves the same distance but in the opposite direction.

∴ As it is possible for displacement to be zero, it is also possible for average velocity to be zero.

The correct option is 2. The solid state is more dense than the liquid state.

The solid form of most substances is denser than the liquid phase so a block of most solids will sink in the liquid but a block of ice floats in liquid water because ice is less dense. Upon freezing the density of water decreases by about 9%. This is due to cooling of intermolecular vibrations allowing the molecules to form steady hydrogen bonds and locking into positions of hexagonal packing upon freezing to ice. These bonds are shorter in the crystal than in the liquid.
