Well the block will still have to deal with gravitational force. So here’s my prediction: Although the block is being dropped at different heights it will accelerate at the same speed no matter what and this is due to the earths gravitational energy (9.8m/s^2 or roughly 10m/s^2) so the only thing that will change is the height that the object is dropped.

It is the bisector of the photosynthesis if you want the nucleustransformation to let you know transpirtation is present for the bisector of photosynthesis and then the nucleus would get a membrane which allowed the photosynthesis synthesise into photos that needs to be taken by photographers

A mass hanged on a spring scale. what is the force exerted by gravity on 700g ?

Ipatiy [6.2K]

Answer:

6.86 N

Explanation:

Applying,

F = mg............... Equation 1

Where F = Force exerted by gravity on the mass, m = mass, g = acceleration due to gravity

Note: The Force exerted by gravity on the mass is thesame as the weight of the body.

From the question,

Given: m = 700 g = (700/1000) = 0.7 kg

Constant: g = 9.8 m/s²

Substitute these values into equation 1

F = 9.8(0.7)

F = 6.86 N

The blood pressure at your heart is approximately 100 mm Hg. As blood is pumped from the left ventricle of your heart, it flows

RoseWind [281]

Answer:

The correct option is c. 75 for this question

Explanation:

The correct option is c. 75 for this question:

Let's see how.

Continuity Equation is given as:

AcVc = AaVa

Where,

Aa = Area of Aorta

Ac = Area of the capillary

Va = Fluid speed in Aorta

Vc = Fluid speed in Capillary

So,

Assuming the fluid is the ideal one/

$\pi$ /4 $Dc^{2}$ Vc= $\pi$ /4 $Da^{2}$ Va

$Dc^{2}$ Vc= $Da^{2}$ Va

Dc = Da x $\sqrt{\frac{Va}{Vc} }$

Dc = 2.5 cm x $\sqrt{\frac{60 cm}{0.07 cm } }$

Dc = 73.192 cm

Dc = 75 approximately

Hence, the diameter of the capillary = 75 cm approximately

The kinetic energy of a baseball that with a mass of 0.140kg is 7 J. What is the baseballs velocity?

Nuetrik [128]

Answer:

10 m/s

Explanation:

Kinetic energy= $\frac{1}{2}$ mv² where m is mass and v is velocity.

We have to make v the subject so we should rearrange the equation

K= $\frac{1}{2}$ mv²

v²= $\frac{K}{0.5*m}$ (use algebra)

v²= 7/0.5×0.140

v²=100

v=√100

v=10 m/s

We can confirm this by using the kinetic energy formula.

K= $\frac{1}{2}$ ×0.140×10²

K= 7 J

Hence it is proved that velocity is 10 m/s
