Answer:
The acceleration of gravity on the Moon is only one-sixth of that on Earth. If we hit a baseball on the moon with the same effort(and at the speed and angle)that we would on earth, the ball would land 6 times as far. The ball on the moon will cover 6 times more distance than Earth.
Explanation:
Speed=distance travelled/Time required speed
Speed=d/t
Acceleration of gravity on earth=9.8 m/s^2
Acceleration of gravity on Moon=1.62 m/s^2
So the maximum height of ball will be the ration of these both gravity.
The volume of the sample is 48.39 cm³.
<h3 /><h3>What is volume?</h3>
The term volume refers to the amount of three-dimensional space taken up by an item or a closed surface
To calculate the volume of the sample, we use the formula below
Formula:
- D = m/v
- v = m/D................ Equation 1
Where:
- m = Mass of the smaple
- D = Density of the sample
- v = Volume of the sample.
From the question,
Given:
Substitute these values into equation 1
Hence, the volume of the sample is 48.39 cm³.

Answer:
Mass of the planet = 6.0 × 
Explanation:
Time period = 2π (R + h) / v
Orbital speed (v) = √GM / (R + h)
T² = 4π² (R + h)² / (GM/ (R + h))
= 4π² (R + h)³ / GM
making m the subject of the formula
m = 4π² (R + h)³ / GT²
= 4π² ( 6.38 × 
+ 230 × 10³ )³ / ( 6.67 × 
) × (89 × 60)²
= 4π² ( 6610000)³ / ( 6.67 × ) × (89 × 60)²
= 5.99 ×
= 6.0 ×
When light passes from one medium to another, part of it continues on
into the new medium, while the rest of it bounces away from the boundary,
back into the first medium.
The part of the light that continues on into the new medium is <em>transmitted</em>
light. Its forward progress at any point in its journey is <em>transmission</em>.
Its direction usually changes as it crosses the boundary. The bending is <em>
refraction</em>.
The part of the light that bounces away from the boundary and heads back
into the first medium is <em>reflected</em> light. The process of bouncing is <em>reflection</em>.
Answer:
c. More intense IR absorption occur for those bonds having greater dipole moment changes with bond lengthening in a vibration.
Explanation:
When the molecules is exposed to the infrared radiation, the sample molecules absorb the radiation of wavelengths (specific to molecule) which causes change in the dipole moment of the sample molecules. The vibrational energy levels of the sample molecules consequently transfer from the ground state to the excited state.
Frequency of absorption peak is determined by vibrational energy gap.
Intensity of absorption peaks is related to change of dipole moment and possibility of transition of the energy levels.
Thus, by analyzing infrared spectrum,abundant structure information of the molecule can be known.
Hence, the correct answer to the question is
c. More intense IR absorption occur for those bonds having greater dipole moment changes with bond lengthening in a vibration.
