Answer:
7.5cm
Explanation:
Velocity vs Time Graph:
When the object is going along the plane with velocity v at a particular time interval t we can explain it's motion via the velocity vs time graph. If the velocity of the object is constant then velocity vs time graph will produce a horizontal straight line. If the amount of differentiation of velocity of the object is positive and constant then the graph shows the linear line whose slope is is the same as the ratio of the change in velocity to the time interval.
Velocity vs time graph:
Is shown in the attached image
A velocity-time graph helps us to estimate the distance traveled by using the area under the graph.
Height of the triangle is the velocity (v) = 0.75m/s
The base of the triangle is the time interval (t) = 0.2sec
Distance travelled = Area of triangle
Distance travelled
= 1/2(V) * t
= 1/2(0.75m/s) * 0.2s
= 0.0075m
=7.5cm
Thus, during one beat blood flows 7.5 cm
Answer:
More force from a football player's throw can accelerate a football faster.
Explanation:
Force = mass * acceleration
Answer:
Chromatid
Explanation:
The chromosome is a (sort of) X shaped structure. A chromatid represents half of this structure, i.e. one "strand" of the structure.
A centromere is the point at which to sister chromatids are connected to form a single chromosome. The centromere is also where the spindle attaches to move chromosomes during mitosis
A vaculole is a plant cell-specific organelle involved in the storage of water and nutrients.
