Which organism is structurally similar to this organism?

Answer:

3.33 m/s

Explanation:

1600 divided by 8 comes out to 200, so supposing we're measuring the speed in terms of Meters Per Second, we would need to divide 200 by 60 to take account of the individual seconds as opposed to simply 200 meters per minute.

Answer:

[tex]25\%[/tex] of the wavelength is between resonances in a closed end tube.

Explanation:

In an one end closed tube, the fundamental resonance occurs when a node is created at the closed end and an antinode is created in the open end.

Thus, for fundamental resonance, the entire length of the tube encloses one-fourth of the wavelength of the standing wave.

The formula to calculate the percentage of the wavelength in a closed end tube is given by

[tex]f=\frac{L}{\lambda}\times100\%........................(1)[/tex]

Here, [tex]f[/tex] is the required percentage, [tex]L[/tex] is the length of the tube and [tex]\lambda[/tex] is the wavelength of the standing wave.

Substitute [tex]\frac{\lambda}{4}[/tex] for [tex]L[/tex] into equation (1) o calculate the required percentage.

[tex]f=\dfrac{\frac{\lambda}{4}}{\lambda}\times100\%\\~~~=25\%[/tex]

the International System of Units, the fundamental units are: The meter (symbol: m), used to measure length. The kilogram (symbol: kg), used to measure mass. The second (symbol: s), used to measure time. The ampere (symbol: A), used to measure electric current.

Answer:

ln physics, Rest is the state at which an object is stationary or not moving with respect to its surroundings, and is said to be at rest. An example would be a book lying on a table.

Answer:

When an object does not change it's position with respect to time it is said to be at rest.

Explanation:

Example- A person sitting on a chair or a book lying on a table.

Please note there is no such thing as absolute rest.

Take the example of a person A sitting in a moving bus. If the observer is in the bus then to him person A is at rest. However if the observer is is outside the bus then person A is in motion as the bus is moving.

Please mark me as brainliest.

Answer:

Explanation:

The formula for this is

[tex]n_1sin\theta_1=n_2sin\theta_2[/tex] where the index of refraction of air is 1.00. Filling in and solving for n2:

1.00sin(25) = n₂sin(13) and

1.00(.423) = n₂(.225) and

[tex]\frac{1.00(.423)}{.225}=n_2[/tex] so

[tex]n_2=1.88[/tex], choice D.

Answer:

(C) 700 N

Explanation:

The given parameters are;

The mass of the mountain climber, m = 100 kg

The angle formed by the rope with the horizontal, θ = 45°

The gravitational field strength, g = 10 N/kg

The weight of the man, W = m × g

∴ W = 100 kg × 10 N/kg = 1,000 N

At equilibrium, we have;

The downward force, the weight of the man, W = The upward force, the vertical component of the tension on the two halves of the rope

We have;

W = T × sin(θ) + T × sin(θ)

∴ 1,000 N = 2 × T × sin(45°)

Therefore, we have;

T = 1,000 N/(2 × sin(45°)) = 707.106781 Newtons

Therefore, the tension in the rope is closest to (approximately) 700 N.

Answer:

in probability theory, a balance equation is an equation that describes the probability flux associated with a Markov chain in and out of states or set of states.

Explanation:

Answer:

Explanation:

35 up 35 down cancel out.

25 forward minus 10 pulling back, so:

25-10

= 15N Right

F = ma

so, we can write it as;

= 5 = m × 20

= 5/20 = m

= 1/4 = m

= 0.25 kg = m

Answer:

It often happens in a circuit which was conducting,and a switch is opened. Any inductance in the circuit will help the voltage increase due to back emf,and this can cause breakdown of the air insulation and an arc can form.

Answer:

water cycle show the continuous movement of water with in the earth and atmosphere

Explanation:

Hope this helps :)

The water cycle is the process through which water evaporates from the earth's surface, rises into the atmosphere, cools and condenses into rain or snow in clouds, and then falls back to the surface as precipitation. Water that falls on land gathers in rivers and lakes, soil, and porous rock strata, and much of it goes back into the seas to evaporate. Water flows in and out of the system.

Complete question:

A hydraulic jack is used to lift a car by applying a force of 120N at the pump piston, if the area of the ram and pump piston are 100cm squared and 1m squared respectively. What is the weight of the car?

Answer:

the weight of the car is 1.2 N

Explanation:

Given;

applied force, F₁ = 120 N

area of the effort (pump), A₁ = 1 m²

area of the load (ram), A₂ = 100 cm² = 1 x 10⁻² m²

let the weight of the car = F₂

The applied pressure is constant and the following equations can be used to calculate the weight of the car.

[tex]P = \frac{F_1}{A_1} = \frac{F_2}{A_2} \\\\F_2 = \frac{F_1 \times A_2}{A_1} \\\\F_2 = \frac{120 \times (1\times 10^{-2})}{1} \\\\F_2 = 1.2 \ N[/tex]

Therefore, the weight of the car is 1.2 N

Answer:

As an object moves faster, its mass increases. ... Because masses approach infinity with increasing speed, it is impossible to accelerate a material object to (or past) the speed of light. To do so would require an infinite force.

Answer:

The one on the left

Explanation:

Answer:

3000 kg*m/s

6000 kg*m/s

Explanation:

p = m*v

p = 150kg*20m/s

p = 3000 kg*m/s

p = 150kg*40m/s

p = 6000 kg*m/s

Answer is 29.1 mol or 525 g

Explanation:

Average speed = total distance/time

That's 2.62 m/s .

You don't want average displacement. You want average velocity.

That's (displacement)/(time).

That's zero, because displacement = 0.

Answer:

Current in the circuit(I) = 0.5 ampere

Explanation:

Given:

Number of resistors = 2 (10 ohm each)

Series of resistors

EMF = 10 volt

Find:

Current in the circuit(I)

Computation:

Total resistance in series = R1 + R2

Total resistance in series = 10 + 10

Total resistance in series = 20 ohm

Current in the circuit(I) = EMF / Total resistance in series

Current in the circuit(I) = 10 / 20

Current in the circuit(I) = 0.5 ampere
