Explanation :
Density of an object can determine using mass and volume. We can measure mass and volume of various sports ball, both regular shaped ball and irregular shaped ball.
Density for regularly shaped ball and that of irregularly shaped ball is different.
Suppose that mass of an object is 100g and the volume is . So, using this data we can find density of that object as
Answer:
In combination, the equatorial bulge and the effects of the surface centrifugal force due to rotation mean that sea-level gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles, so an object will weigh approximately 0.5% more at the poles than at the Equator.
Answer:
Detecting kidney stones and cancer, visualizing fetus in the womb
Explanation:
Ultrasound technology can be used in detecting kidney stones and cancer throat and also visualizing a fetus in the womb. The use of ultrasound for detecting kidney stones started around 1961. Ultrasound has also been used in detecting various types of cancer including throat cancer. The use of ultrasound in knowing the gender of fetus in hospitals has been used for a long time. However, it's not used for cleaning dirty surgical tools. therefore, choice A, D and E apply.
- Detecting kidney stones
- Detecting throat cancer
- Visualizing a fetus in the womb
Answer:
OR
Explanation:
From the question we are told that
The constant speed of the balloon is
The height of the balloon is
The initial speed of the pellet is
Generally the height of the balloon at the point it is the same altitude with the pellet is mathematically represented as
Note: vt is the distance covered by the balloon before the pellet got to it
Generally the height of the pellet when it is the same height with the balloon is mathematically represented using kinematics equation
So
H = s
=>
=>
=>
using the quadratic formula to solve the above equation
From the quadratic formula calculation
OR
So the height of this two place above the ground is mathematically evaluated as
OR
