Scavenger can help break down or reduce organic material into smaller pieces. These smaller pieces are then eaten by decomposers.

They may be called scavengers. They assist damage down or lessen organic cloth into smaller portions. these smaller portions are then eaten through decomposers. Decomposers consume useless materials and spoil them down into chemical components.

In the event that they weren't within the ecosystem, the plant life could no longer get essential vitamins, and dead count and waste might pile up. There are  sorts of decomposers, scavengers and decomposers. Scavengers are animals that locate useless animals or flora and consume them. while they consume them, they spoil them into small bits.

What is the difference among a detritivore and a scavenger?   Detritivores eat organic debris that they discover, from any organisms. Scavengers consume the soft tissues of dead/decaying animals. Detritivores consume organic particles that they discover, from any organisms.

Dividing 120m and 8.0 m / s makes sense because 120 m is the distance travelled East and 8 m / s is velocity travelled East.

Using the velocity value of 6 m / s with 120 m would have been wrong because it is the South velocity. If you wanted to use 6 m / s velocity value, you have to find the distance travelled South. Since there is no acceleration, the time taken to travel East, South and the resultant distance will all be the same.

v = d / t

v = Velocity

d = Distance

t = time

For East,

t = 120 / 8

t = 15 s

tan θ = Vs / Ve

tan θ = 6 / 8

θ = 36.9°

For south,

tan 36.9° = d / 120

d = 0.75 * 120

d = 90 m

t = 90 / 6

t = 15 s

As you can see both time values are same.

Therefore, dividing 120m and 8.0 m / s makes sense because 120 m is the distance travelled East and 8 m / s is velocity travelled East.

When a separate branch-circuit is run to a wall mounted oven, or to a counter-mounted cooking unit, the branch circuit size is based on of the nameplate rating of the appliance.

The ratings are shown in watts on the appliance nameplate. The circuit must be sized to provide the required number of amperes to operate the appliance at its nameplate rating.

One ampere is defined as the current that flows through a conductor when a potential difference of one volt is applied across it. The ampere is thus equivalent to the coulomb, the SI unit of charge. The ampere was originally defined as one tenth of the unit of electric current in the centimetre–gram–second system of units.

The speed of the object is increasing. The force is decreasing, but since the surface is frictionless, the object continues to accelerate in the direction of the force.

Since the force is in the same direction as the velocity (moving to right), hence speed of the object will increase with time. The decrease in magnitude of force will only result in the decrease in the rate of increase of speed but the speed in total will still increase.

Electromagnetic radiation is a form of energy that exhibits wavelike behaviour as it travels through space.

Examples of EMR include ultraviolet light, infrared light, microwaves, and radio waves.

In terms of science, electromagnetic radiation (EMR) is made up of electromagnetic (EM) field waves that travel over space while carrying radiant electromagnetic energy. It consists of X-rays, gamma rays, microwaves, infrared, visible light, ultraviolet, and radio waves. These waves are all a component of the electromagnetic spectrum.

Electromagnetic waves, which are synchronized oscillations of the electric and magnetic fields, are the traditional form of electromagnetic radiation. Due to the periodic alteration of the electric or magnetic field, electromagnetic radiation or waves are produced. Different wavelengths of the electromagnetic spectrum are created depending on the way this periodic change takes place and the power generated. Electromagnetic waves move at the speed of light, typically abbreviated as c, in a vacuum.

The Charge on smaller of the two charges is 1.747 × 10⁻⁷ C .

When two charges come together, an attractive force occurs for opposite charges and a repulsive force for similar charges. Coulomb's law can be used to calculate the electrostatic force between two charges if the distance between them is known.

Coulomb's Law defines the following equation for this: F.E = Kₑq₁ q₂/r²

Where,

F.E --> electrostatic force in Newton

Kₑ---> Coulomb constant

q₁---> charge of the larger charge in coulombs

q₂---> charge of the smaller charge in coulombs

r ---> distance between the objects in meters

we have given that ,

charge on larger charge(q₁) = 9.56 × 10⁻⁶C

Coulomb constant (Kₑ) = 8.988×109 Nm²C⁻²

distance between two charges = 0.45 m

repulsive force between charges = 0.015 N

putting all the values in above formula we get, 0.015 = (8.988×10⁹ Nm²C⁻² × q₂ × 9.56×10⁻⁶ C)/(0.45)²

=> q₂ = 1.747 × 10⁻⁷ Coulomb

When Isabel pushes a shuffleboard disk, accelarating it to a 6,5 m/s before releasing it, the shot will stop in the 10 point section of the board.

The average speed is calculated by dividing the total distance traveled by the total time it took to travel that distance. Speed is the rate at which something moves at any given time. Average speed is the average rate of speed over the course of a journey. .

Velocity is the directional speed of a moving object as an indication of its rate of change in position as observed from a specific frame of reference and measured by a specific time standard.

Since Isabel pushes a shuffleboard disk, accelarating it to a 6,5 m/s before releasing and the coefficient of kinetic friction between the disk and concrete court is 0.31, this will be illustrated thus:

The initial speed of disk = 6.5 m/s

deceleration of disk = 0.31*9.8=3.038 m/s²

Let the distance travelled by disk before coming to stop s

s=6.52/(2*3.038)

Buoyancy force:

The buoyant force is the upward force exerted on an object wholly or partly immersed in a fluid. This upward force is also called Upthrust. Due to the buoyant force, a body submerged partially or fully in a fluid appears to lose its weight, i.e. appears to be lighter.

Formula to calculate buoyancy forces:

B = ρgV

ρ= fluid density

g = acceleration due to gravity

V = fluid volume

V = πr²L

So;

B = ρgπr²L

Given data:

g = 9.8 m/s²

r = 15 cm = 0.15m
