Answer: Option D and E
Explanation: Across the electromagnet spectrum, the frequency increases but the wavelength reduces.
This implies that radio waves have the longest wavelength but the smallest frequency, while gamma rays have the shortest wavelength but the highest frequency.
This implies that there is an inverse relationship between wavelength and frequency.
Of all the technologies listed above, wireless internet has the highest frequency hence making it have the shortest wavelength.
Also by comparing values from the data given to us above, it is possible for some wireless internet device to operate within the same frequency range of the microwave.
Magnitude of acceleration
Explanation:
We know that acceleration can increase depending in the force applied on an object, any object with a greater mass will apply a greater force. F = M(a).
Answer:
The first option, "The more mass an object has, the greater the gravitational pull.
"
Explanation:
Newton's Law of Gravity states that 
, where G is the gravitational constant, 
and 
are the masses of the two objects, and <em>r</em> is the distance between the objects' centers. Because the objects' masses are in the fraction's numerator, they are directly proportional to 
, and increasing the mass of one or both objects increases the gravitational pull.
Please have a great day! I hope this helps you understand the question!
The power delivered by the motor lift in elevating the 10 passengers at the speed of 16.8 m/s is 205800 Watts
<h3>What is power? </h3>
Power is simply defined as the rate at which energy is consumed. It can be expressed mathematically as
Power (P) = Force (F) × velocity (v)
P = Fv
<h3>How to determine the force </h3>
- Mass (m) = 1250 Kg
- Acceleration due to gravity (g) = 9.8 m/s²
F = ma
F = 1250 × 9.8
F = 12250 N
<h3>How to determine the power </h3>
- Velocity (v) = 16.8 m/s
- Force (F) = 12250 N
P = Fv
P = 12250 × 16.8
P = 205800 Watts

Explanation:
What is IEEE 802.11?
IEEE 802.11 is a set of WLAN standards for communication developed by the Institute for Electrical and Electronics Engineers (IEEE) and is unarguably most widely used WLAN technology.
Features: IEEE 802.11a
- The operating frequency band is 5 GHz.
- The maximum theoretical data rate is 54 Mbps, the typical throughput is around 25 Mbps and minimum data rate is 6 Mbps.
- It can support 64 users per access point.
Features: IEEE 802.11b
- The operating frequency band is 2.4 GHz.
- The maximum theoretical data rate is 11 Mbps but typical throughput is around 6 Mbps and minimum data rate is 1 Mbps.
- It can support 32 users per access point.
Wireless Coverage IEEE 802.11a Vs IEEE 802.11b:
- Signal coverage is one of the most important factors among users.
- The transmission range of IEEE 802.11a is not greater than 100 ft in indoor setting whereas IEEE 802.11b has a superior performance in this regard with transmission range up to 150 ft in indoor setting.
- The data rate has a direct relation with the access point coverage area, a higher data rate means less coverage area and a lower data rate results in increased coverage.
