Isotope is each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei.

It means it has same atomic number but different mass number.

isotopes are the same element, but have different numbers of neutrons (but still have the same number of electrons and protons), hence have a different mass number.

Which of the following lists the typical steps of the scientific method in the

irinina [24]

B. Ask a question - Hypothesize - Experiment - Analyze - Draw a conclusion

Explanation:

The scientific method is a systematic approach in which investigations are conducted in science.

It follows systematic manner;

An observation in nature is made using the senses.
Questions are then asked about such observations. This is the inquiry phase.
A hypothesis is then formula to predict what might cause the observation.
Experiments are then conducted
The results are analyzed and a conclusion is drawn

We need to consider for this exercise the concept Drag Force and Torque. The equation of Drag force is

$F_D = c_D A \frac{\rho V^2}{2}$

Where,

F_D = Drag Force

$c_D$ = Drag coefficient

A = Area

$\rho$ = Density

V = Velocity

Our values are given by,

$c_D = 0.5$ (That is proper of a cone-shape)

$A = 9m^2$

$\rho = 1.2Kg/m^3$

$V = 6.5m/s$

Part A ) Replacing our values,

$F_D = 0.5*9*\frac{1.2*6.5^2}{2}$

$F_D = 114.075N$

Part B ) To find the torque we apply the equation as follow,

$\tau = F*d$

$\tau = (114.075N)(7)$

$\tau = 798.525N.m$

What happens to the force needed to stretch a rubber band when putting it on a stack of papers?

zmey [24]

Answer:the force is needed to stretch it farther.

Explanation: the definition of force is push or pull so imagine stretching a rubber band your pulling the band which means you increase the force.
