Bees can see into the ultraviolet region of the electromagnetic spectrum. Compared with humans, bees can sense electromagnetic waves that have a lower frequency and a shorter wavelength. a higher frequency and a longer wavelength. a lower frequency and a longer wavelength. a higher frequency and a shorter wavelength.
Answer:
a higher frequency and a shorter wavelength.
Explanation:
The correct answer would be a higher frequency and a shorter wavelength.
The visible region of the electromagnetic spectrum lies between 400 and 750 nm while the ultraviolet region lies between 300 and 400 nm. Hence, it means that bees are able to see at a shorter wavelength compared to humans.
There is an inverse relationship between the wavelength and frequency of a wave. the longer the wavelength of a wave, the shorter the frequency, and the shorter the wavelength, the higher the frequency. The means that bees are not just able to see at a shorter wavelength but at a higher frequency compared to humans.

Suppose A = B"Cm, where A has the dimensions LT, B has dimensions L²T-1, and C has dimensions LT2. Then the exponents n and have the values
Complete Question:
Suppose [tex]A = B^n C^m[/tex], where A has the dimensions LT, B has dimensions L²T⁻¹, and C has dimensions LT². Then the exponents n and m have the values
Answer:
The value of n = ¹/₅
The value of m = ³/₅
Explanation:
Given dimensions;
A = LT
B = L²T⁻¹
C = LT²
The values of n and m are calculated as follows;
[tex]LT = [L^2T^{-1}]^n[LT^2]^m\\\\L^1T^1 = [L^{2n}T^{-n}]\times [L^mT^{2m}]\\\\L^1 \times T^1 = [L^{(2n+m)}] \times [T^{(-n +2m)}]\\\\1 = 2n + m -----(1)\\\\1 = -n + 2m ----(2)\\\\from \ (1); \ m = 1-2n, \ \ substitute \ the \ value \ of \ m \ in\ (2)\\\\1= -n +2(1-2n)\\\\1 = -n + 2-4n\\\\1-2 = -5n\\\\-1 = -5n\\\\1= 5n\\\\n = \frac{1}{5} \\\\m = 1 - 2n\\\\m = 1 - 2(\frac{1}{5} )\\\\m = 1- \frac{2}{5} \\\\m = \frac{3}{5}[/tex]

A rain cloud contains 4.2 × 10^5 kg of water vapor. How long would it take for a 4000 W pump to raise the same amount of water to the cloud’s altitude, 3.500 km?
Answer:
it will take 1,000.42 hours to raise the same amount of water.
Explanation:
mass of the water to be raised, m = 4.2 x 10⁵ kg
power applied in lifting the water, P = 4000 W
height through which the water will be lifted, h = 3.500 km = 3,500 m
The power applied the water is given as follows;
[tex]Power = Force \times Velocity\\\\P = FV\\\\P = ma \ \times \ V\\\\P = ma \ \times \ \frac{d}{t} \\\\P = mg \ \times \ \frac{h}{t} \\\\P = \frac{mgh}{t} \\\\t = \frac{mgh}{P} \\\\t = \frac{4.2\times 10^5 \times 9.8 \times 3,500}{4,000} \\\\t = 3,601,500 \ s = 1000.42 \ hours[/tex]
Therefore, it will take 1,000.42 hours to raise the same amount of water.
A4.0 μF capacitor is connected in series with a 2.0 MΩ resistor, and this combination is connected across an ideal 44.0 V DC battery. Initially the charge on the capacitor is zero. What is the current in the circuit when the capacitor has reached 80 % of its maximum voltage?
Answer:
i = 17.6 10⁻⁶ A
Explanation:
The charge of a capacitor in a series circuit is
i = [tex]\frac{v_o}{R}[/tex] [tex]e^{ - \frac{t}{RC} }[/tex] (1)
R i = V₀ e^{ - \frac{t}{RC} }
[tex]\frac{V}{V_o}[/tex] = e^{ - \frac{t}{RC} }
they tell us that the voltage is 80% bone
[tex]\frac{V}{V_o}[/tex] = 0.80
we substitute
0.80 = e^{ - \frac{t}{RC} }
ln 0.80 = [tex]- \frac{t}{RC}[/tex]
t = - RC ln 0.80
in the problem they give the value of R = 2.0 10⁶ Ω and C = 4.0 10⁻⁶ F
t = - 2 10⁶ 4 10⁻⁶ ln 0.8
t = 1,785 s
we substitute in equation 1
i = [tex]\frac{44.0}{2 \ 10^6}[/tex] [tex]e^{- \frac{1.785}{2 \ 4 } }[/tex]
i = 22 10⁻⁶ [tex]e^{-0.2231}[/tex]
i = 17.6 10⁻⁶ A
How do you find the volume of a rectangular brick?
Answer:
Multiply the length, width and height of the brick to calculate its volume.
Explanation:
To find the volume of a rectangular brick, you need to multiply its length, width, and height.
The rectangular brick is 400 cubic centimeters (cm³).
The formula to calculate the volume of a rectangular prism (which includes a rectangular brick) is:
[tex]\[ \text{Volume} = \text{Length} \times \text{Width} \times \text{Height} \][/tex]
Let's assume the length of the rectangular brick is 10 cm, the width is 5 cm, and the height is 8 cm. Plugging these values into the formula, we get:
[tex]\[ \text{Volume} = 10 \, \text{cm} \times 5 \, \text{cm} \times 8 \, \text{cm} \][/tex]
Now we can calculate the volume:
[tex]\[ \text{Volume} = 400 \, \text{cm}^3 \][/tex]
Therefore, the volume of the rectangular brick is 400 cubic centimeters (cm³).

How can you separate chalk from
chalky water?
Answer:
Yes

Krishne wants to measure the mass and volume of a key. Which tools should she use?
A. a balance and a beaker of water
B. a balance and a meter stick
C. a beaker of water and a ruler
D. a ruler and a meter stick
Answer:
A balance and a beaker of water!
Explanation:
Krishne wants to measure the mass and volume of a key. The tools that are to be used are – a balance and a beaker of water.
Mass will be represent with the amount of matter that is in an object. This will be measured in terms of kilogram. The mass can easily be measured with balance.
Volume is the quantity of matter that is in the object. This is measured in terms of cubic meter. If you drop the key in a beaker of water, the water inside the beaker will increase and this increases the volume of water that will be equal to volume of key.
An object accelerates at 32 m/s² when a force of 71 N is applied to it. What is the object’s mass?
Answer:
2.21875 kg
Explanation:
FORCE = MASS x ACCELERATION so to find mass we divide both sides by acceleration. M=F/A
SO 71N/32m/s²=2.21875 kg.
remember N=kgm/s² so m/s² is canceled by m/s² the remaining is kg
The answer is mass= 2.21 kg
The first step is to write out the parameters given in the question
acceleration= 32 m/s²
force-= 71 N
The formula for calculating the object's mass is
mass= force/acceleration
= 71/32
= 2.21 kg
Hence the object's mass is 2.21 kg

A boy of mass 50 kg walks up a staircase of 10 steps each 15 cm high. Calculate the work done.
Answer:
735 J
Explanation:
Total height reached(displaced)=10x15 cm
= 10 x 15/100 m
= 1.5 m
Workdone = F.S (force x displacement)
Here, the boy is traveling against the gravitation force(=mg) , and traveled a height of 1.5m
Hence,
Workdone = 50 x 9.8 x 1.5 J
= 735 J
Answer:
750J
Explanation:
Solution;
M=50kg, g=10m/s
Distance=15×10÷100
=1.5m
W=M×g×h
=50×10×1.5
=750J
