Answer:
Spectra type M
Explanation:
mass spectrum is simply an intensity vs. m/z (mass-to-charge ratio) plot representing a chemical analysis. Hence, the mass spectrum of a sample is a pattern representing the distribution of ions by mass (more correctly: mass-to-charge ratio) in a sample. It is usually acquired using an instrument called a mass spectrometer. Not all the mass spectra of a given substance are same.
Answer:
The mass of the other worker is 45 kg
Explanation:
The given parameters are;
The gravitational potential energy of one construction worker = The gravitational potential energy of the other construction worker
The mass of the lighter construction worker, m₁ = 90 kg
The height level of the lighter construction worker's location = h₁
The height level of the other construction worker's location = h₂ = 2·h₁
The gravitational potential energy, P.E., is given as follows;
P.E. = m·g·h
Where;
m = The mass of the object at height
g = The acceleration due to gravity
h = The height at which is located
Let P.E.₁ represent the gravitational potential energy of one construction worker and let P.E.₂ represent the gravitational potential energy of the other construction worker
We have;
P.E.₁ = P.E.₂
Therefore;
m₁·g·h₁ = m₂·g·h₂
h₂ = 2·h₁
We have;
m₁·g·h₁ = m₂·g·2·h₁
m₁ = 2·m₂
90 kg = 2 × m₂
m₂ = (90 kg)/2 = 45 kg
The mass of the other construction worker is 45 kg.
Answer:
The speed and direction of the apple is 1.448 m/s and 66.65°.
Explanation:
Given that,
Mass of apple = 0.110 kg
Speed = 1.13 m/s
Mass of orange = 0.150 kg
Speed = 1.25 m/s
Suppose we find the final speed and direction of the apple in this case
Using conservation of momentum:
Before:
In x direction,
In y direction = 0
After:
is velocity of the apple in the y direction
is the velocity of the apple in the x direction
Momentum again:
In x direction,
In y-direction,
We need to calculate the speed of apple
Put the value into the formula
We need to calculate the direction of the apple
Using formula of angle
Put the value into the formula
Hence, The speed and direction of the apple is 1.448 m/s and 66.65°.
