A vehicle travels from a 30m marker to a 100m marker. What is the change in distance

alexgriva [62]

70 meters is your answer

Note that the beginning is the 30 meter mark, and the ending is the 100 meter mark. Subtract the beginning amount from the end:

100 - 30 = 70

The vehicle traveled 70 meters.

The biodiversity of cultivated crops is currently under threat

Angelina_Jolie [31]

C. Establishing a seed bank with a variety of seeds of

different crop species

Explanation:

Establishing a seed bank with a variety of seeds of different crop species is a cooperative behavior that would best enable humans to prevent the problem of loss of biodiversity of cultivated crops.

Modern agricultural practices is profit driven and centered on mono-cropping.
Mono-cropping is an agricultural practice in which only one crop type is cultivated on a mechanized scale.
Mono-cropping leads to less diversity of crop species as just only the cultivation of economically important crops are encouraged.
In order to avert the menace that comes along with mono-cropping, seed banks are viable place to keep and protect other plant species from going into extinction.
Seed banks provides a preservation of different plant species by focusing on storing their viable seeds.

What change takes place in a wave when the frequency of the wave increases?

Musya8 [376]

The answer is C. As the frequency of the waves increases, a greater number of wavelengths pass a given point per second. From the wave formula, we see that there is an indirect relationship between frequency and the wavelength. thus, as the frequency increases the wavelength decreases resulting to a smaller distance between the waves which will show greater number of wavelengths between waves.

1.3 kg of water, at an initial temperature of 25oC, is heated at a rate of 100 W in a well-insulated container. How much time (i

Leviafan [203]

Answer:

68.25 minutes.

Explanation:

Power = Energy/time or

Power = Heat/time

P = Q/t....................... Equation 1

Q = Pt ........................ Equation 2

Where Q = quantity of heat, P = power, t = time.

Also,

Q = cm(t₂-t₁) ................. Equation 3

Where c = specific heat capacity of water, m = mass of water, t₁ = initial temperature of water, t₂ = final temperature of water.

substitute equation 2 into equation 3

Pt = cm(t₂-t₁) ............... Equation 4

make t the subject of the equation

t = cm(t₂-t₁)/P................ Equation 5

Given: P = 100 W, m = 1.3 kg, t₁ = 25 °C, t₂ = 100 °C.

Constant: 4200 J/kg.K

Substitute into equation 5

t = 1.3(4200)(100-25)/100

t = 409500/100

t = 4095 seconds

t = (4095/60) minutes = 68.25 minutes.

Hence the time it will take the water to reach boiling point = 68.25 minutes
