Answer:

D. different isotopes for the same element will always have the same numbers of neutrons.

Explanation:

An isotope is the different variant of an element that has different number of neutron. There are various elements found in nature that have different isotopes.

Number of neutrons present in atom is different for the same element which makes the mass of one isotope different from the another.

Example of such isotope : Isotope of hydrogen are Protium, Deuterium and Tritium.

The force pushing down is the force of Gravity. On a chair it is in perfect balance with the force pushing up (the normal force)

in terms of magnitude
FN = FG = mg

the forces are in opposite direction

Can a falling object reach terminal velocity in outer space? Explain.

Damm [24]

Ith air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 53 m/s (195 km/h or 122 mph) for a human skydiver. ... (On the Moon, the gravitational acceleration is much less than on Earth, approximately 1.6 m/s2.)

Physical data is often used in the court system. In fact, police officers use radar to determine your speed when you are driving

Mashcka [7]

The driver is telling the truth, the radar gun must have been set incorrectly to record relative velocity.

The given parameters:

Speed of the driver observed by the stationary police officer, Vo = 44.7 m/s
Speed of the driver, V = 26.8 m/s.
Speed limit = 60 mph

The speed limit of the driver in meter per second is calculated as follows;

$= 60 \ \times \frac{miles}{hour} \times \frac{1609.34 \ m}{1 \ mile} \times \frac{1 \ hr}{3600 \ s}\\\\= 26.82 \ m/s$

From the speed limit, it is obvious that the driver's speed is within the limit. Thus, we can conclude that the driver is telling the truth, the radar gun must have been set incorrectly to record relative velocity.

if the radius of the capillary tube is doubled, what changes will take place in the hieght of rise of liquid with capacity tube

tangare [24]

Explanation:

The height of the rise of liquid with capillary tube is given by the formula as follows :

$h=\dfrac{2S\cos\theta}{r\rho g}$

Where

r is radius

It is clear that the height of the rise of liquid is inversely proportional to the radius of the capillary tube.

If the radius of the capillary tube is doubled, it means the height of rise of liquid with capillary tube become half.
