Answer:
Explanation:
yes object can move through a distance and can have zero displacement
as displacement is the shortest distance between two points eg: if a person has moved a distance of 20 m and comes back to his original place by moving back 20m in such a case distance moved by the person is 40m but his displacement is 0 as shortest distance covered by him is 0 as he is in his original place
Yes, it is possible for a body to have traveled a distance yet have a displacement of zero.
Distance traveled by a body is the length of the path covered by it.
On the other hand displacement of a body is the shortest distance between the initial and the final point of a body.
When a body is traveling such that it ends at the point from where it started its journey, it covers a distance but the displacement of the body is zero.
So a body that has moved through a distance can have zero displacement.
Average Acceleration = (change in speed) / (time for the change)
Change in speed = (ending speed) - (starting speed)
= 15 m/s - 24 m/s = -9 m/s
Acceleration = (-9 m/s) / (12 sec) = - 0.75 m/s² .
Double , the force is pushed against the cart added by mass is enough to double the acceleration , and thank u :)
Answer:
Ethanol-filled thermometers are used in preference to mercury for meteorological measurements of minimum temperatures and can be used down to −70 °C (−94 °F). The physical limitation of the ability of a thermometer to measure low temperature is the freezing point of the liquid used.
Answer:
Sonography-A process in which machine generate a high frequency sound waves that bounch back or reflected from the surface creating echos that are then processed into images .
Ultrasound scans are used to detect problems in the liver, heart, kidney, or abdomen.
