The phenomenon that causes stars and galaxies to appear red when they are moving away from us is called "The Doppler Effect". (Option A)

How would one define the Doppler Effect?

We've known that most other galaxies are moving away from us since 1929, when Edwin Hubble revealed that the Universe is expanding. Light from these galaxies is displaced to longer (and hence redder) wavelengths it is red when it is shifted.

The Doppler Effect is illustrated through redshift. As an item travels away from us, the sound or light waves it emits are stretched out, resulting in a lower pitch and a shift to the red end of the electromagnetic spectrum, where light has a longer wavelength.

The cost of the Costa Rica and Columbian coffee are $200 and $150 respectively

What are the amounts of each of the coffee?

Let us recall that we are told that a coffee shop sells special blend of coffee that comes in a 100-pound bag and costs $3.50 per pound. It is a mix of coffee from Costa Rica at $4 per pound and Columbian at $3 per pound.

Let the number of pounds of the Costa Rica coffee be x and the number of pounds of the Columbian coffee be y.

Given that;

x + y = 100 ------- (1)

4 x + 3 y = 350 ------- (2)

y = 100 - x ----(3)

Substitute (3) into (2)

4x + 3(100 - x) = 350

4x + 300 - 3x = 350

x + 300 = 350

x = 350 - 300

x = 50

From(1)

50 + y = 100

y = 50

Then;

Cost of the Costa Rica coffee = 4(50) = $200

Cost of the Columbian coffee = 3(50) = 150

Explanation:

The volume of water in each graduated cylinder is calculated with the formula; π × r² × h. The volume of graduated cylinder usually start from 10 mL to 1000 mL

The volume of a graduated cylinder

A graduated cylinder is an item of glass laboratory equipment consisting of a tall, narrow cylinder with a scale, or graduations marked up its length, which is used to measure liquids and solutions fairly accurately, but not precisely.

The volume of a graduated cylinder can be calculated using the formula;

π × r² × h

Where,

π = pir = radius of the cylinderh = height of the cylinder

For instance, if a graduated cylinder has a radius of 5 ml and a height of 7 ml,

Volume of the graduated cylinder = π × r² × h

= 3.14 × 5² × 7

= 3.14 × 25 × 7

= 549.5 cubic ml

In conclusion, the volume of the graduated cylinder given in the instance is 549.5 cubic ml

There is a writing section, a reading section, a math no calculator section, and a math with calculator section. For the writing section, make sure you know your grammar rules. For the reading section, watch out for the historical passages that take longer to read - plan your time accordingly. For the math sections, they aren't like regular math that's taught in school. It requires a lot more thinking - think then do math - don't just start with a wall of math. Sometimes you won't even need to do calculations - think first then do math to go through all the problems quickly before the time ends. There are grid in problems in the math sections, meaning no options to choose.

If the block of wood is moved to a distance of 3 meters, the amount of work done is equal to 38.97 Joules.

What is work done?

The work done (W) by an object can be calculated by multiplying the force acting on it by the perpendicular distance covered by the physical object. This ultimately implies that, work done (W) and energy (E) have the same unit i.e Joules (J).

Mathematically, the work done (W) by an object can be calculated by using this formula:

Work done (W) = force × distance

Work done (W) = mgdcosθ or Fdcosθ

Substituting the given parameters into the formula, we have;

Work done (W) = 15 × 3 × cos30

Work done (W) = 15 × 3 × 0.8860

Work done (W) = 38.97 Joules.
