Answer:
An average male lives 27,375 Days
Answer: the correct option is D (17m).
Explanation: The farthest distance at which a typical "nearsighted" frog can see clearly in air is 17m.
Answer:
See explanation
Explanation:
Range of a projectile is given by; U^2sin2θ/g
When θ = 45°
The maximum range is obtained as;
Rmax = U^2/g
Maximum range on earth = RME = U^2/g
Maximum range in the moon= RMM =U^2/g/6
Maximum range in Mars = RMMA = U^2/0.38g
a)
RME/RMM = U^2/g/U^2/g/6
RME/RMM = 6
But RME = 3 m
RMM = 3 * 6 = 18 m
b)
RME/RMMA =U^2/g/U^2/0.38g
RME/RMMA = 1/0.38
But RME = 3 m
RMMA = 3/0.38
RMMA = 7.9 m
Answer:
Description.
Explanation:
Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.
This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.
Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement, position, etc.
A reference point refers to a location or physical object from which the motion (movement) of another physical object or body can be determined.
For example, a point on a map is considered to be a reference point because it represents the starting point of an object or person in motion.
Hence, if the reference point changes, the description of position changes, but the actual position does not change.
