<u>We are given:</u>
Weight on Earth = 300 N
Value of g on the planet = 4 ft/s²
<u>Converting to m/s: </u>
4 ft/s² * (1 m / 3.3 ft) = 13.2 m/s²
<u>Mass of the object:</u>
We know that:
Weight = Mass * g
<em>replacing the given values</em>
300 = Mass * 9.8 [g = 9.8 m/s²]
Mass = 300/9.8
Mass = 30.6 kg <em>(approx</em>
<u>Weight on the other Planet:</u>
Weight = Mass * g(on that planet)
Weight = 30.6 kg * 13.2 m/s²
Weight = 403.92 N
Answer:
a. 340.13 m/s b. 680.26 m/s c. our wavelength doubles
Explanation:
a. speed of wave, v = fλ were f = frequency = 301 Hz and λ = wavelength = 1.13 m.
v = fλ = 301 Hz × 1.13 m = 340.13 m/s
b. If we double the frequency then f = 2 × 301 Hz = 602 Hz
v = fλ = 602 Hz × 1.13 m = 680.26 m/s
c. If the speed of the wave is still 340.13 m/s, if we cut the frequency in half, then frequency now equals f = 301 Hz/2 = 150.5 Hz.
Since v = fλ,
λ = v/f = 340.13 m/s ÷ 150.5 Hz = 2.26 m.
Since our initial wavelength λ₀ = 1.13 m,
λ/λ₀ = 2.26 m/1.13 m = 2.
So, λ = 2λ₀ our wavelength doubles
The kinetic energy of the person would be 1062.5J
<u>Explanation:</u>
Given:
Mass of the person, m = 85kg
Velocity, v = 5m/s
Kinetic energy, KE = ?
We know,
Substituting the value in the equation:
Therefore, the kinetic energy of the person would be 1062.5J
Answer:
Lipids
Explanation:
Membrane mostly considered largely of lipid bilayer. It is the double called phospholipids. These glycolipids contains the chain of fatty acids. These fatty acids determines that whether the sheet of membrane is formed around the vesicles or not.
Lipids that provide a liquid to the membrane cells. The consistency of liquid appears as the light oil. It consists of fatty acid chain that includes many fatty acid molecules for example oxygen that permeate from the membrane. These fatty acids repels large molecules fatty acids such as sugar, electrical charged ions etc.
Answer:
32 seconds
Explanation:
Time is equals to distance divided by speed, so, time is inversely proportional to speed that means as the speed increases the time taken by the sprinter decreases.
Here, Speed is given which is 10 meters per second
Distance is 320 meters
By putting the values of speed and distance in the formula of time we will get the answer of time taken by the sprinter which is 32 seconds.
