Electromagnetic radiation is more common than you think. Radio and TV stations emit radio waves when they broadcast their progra
meriva

Answer:

1) i. All these technologies use radio waves, including high-frequency microwaves.

ii. Microwave ovens emit in the same frequency band as some wireless Internet devices.

2. B. The earth absorbs visible light and emits radiation with a longer wavelength.

Explanation:

Electromagnetic radiations are generated when there is an interference between electric and magnetic fields traveling at right angles to each other. All electromagnetic waves forms a spectrum with respect to their frequency and wavelength. The higher the wavelength, the lower the frequency.

All these waves move with the same and constant speed, but are generated from different sources. From the given applications, X-ray has a high frequency, but low wavelength.

In the second case, infrared waves have longer wavelength than visible light.

Ice fishermen sit on top of frozen lakes in the winter and catch fish in the liquid water below through holes cut in the ice she
melomori [17]

Answer:

This is because below 4°c, water unlike other materials becomes less dense when it's temperature is further lowered.

Explanation:

Due to the unusual nature of water; at about 4°c, the behavior of the density of water in relation to its temperature reverses. This means that water becomes less dense as it becomes colder below 4°c. The colder parts therefore floats to the top of the water body while the warmer part sinks allowing the top to freeze and the remaining body below to remain in its liquid state.

The freezing of the top of the lake alone protects the remaining depth of water from freezing by acting as an insulator and preventing further heat loss from the water to the ambient space. If this had not been the case, and water froze all through, marine lives will freeze to death and it will be more difficult to melt the ice come the next summer.

This behavior is due to the hydrogen bonding of the water molecules.

Suppose a consumption function is given as c = $500 0.75yd. the marginal propensity to consume is:______
kobusy [5.1K]

In the the case above, if the consumption function is: C = $500 + 0.75 × YD, from the equation, the The marginal propensity to consume is option C) 0.75.

<h3>What is MPC?</h3>

The marginal propensity to consume which is MPC is the aspect of each extra money that is dollar of a household's income that is said to be used, consumed or spent.

Note that Consumer behavior in regards to saving or spending has a very vital impact on the economy of a country.

From the formula given, the breakdown is:

YD = disposable income.

Autonomous consumption = $500.

The marginal propensity to consume  = 0.75.

Therefore, In the the case above, if the consumption function is: C = $500 + 0.75 × YD, from the equation, the The marginal propensity to consume is option C) 0.75.

See full question below

Suppose that the consumption function is: C = $500 + 0.75 × YD

(Scenario: Consumption Spending) The marginal propensity to consume is:

A) $500.

B) 0.

C) 0.75

D) 0.2.

When does the difference between two vectors equal to zero ?
SVEN [57.7K]

Answer: Yes, two vectors of equal magnitude that are pointing in opposite directions will sum to zero

Explanation: Two vectors of unequal magnitude can never sum to zero. If they point along the same line, since their magnitudes are different, the sum will not be zero.

A man pushes a 49 kg mower with a force of 650 N at a downward angle of 35° as shown in the picture to the right. If the mower e
ElenaW [278]

Answer:

a = 0.8m/s^2

F = 39.28 N

Explanation:

Sum of forces in X direction = 650cos(35)N-493.249N

Sum of forces in X direction= 39.28 N

F = m*a

a = F/m

a = 39.28N/49kg

a = 0.8 m/s^2
