Answer: The unit of weight is Newtons.

Explanation:

Mass of an object is the amount of matter contained in the body. It is measured in units of g, kg and mg.

Weight of an object is the force acting on an object by virtue of its mass.

weight= $m\times g$

m = mass

g= acceleration due to gravity

Putting in the values we get,

weight= $kg\times m/s^2=kgms^{-2}=N$

$1kgms^{-2}=1Newton(N)$

Thus weight is expressed in units of Newton in S.I system.

Weight of any object is given as follows:

Weight = mass*acceleration due to gravity

The unit of weight is N, while the unit of mass if kg.

In the given statement the unit is kg means the correct statement is this rock mass is 8 kilo-grams

Zinc oxide helps protect the lifeguards from damaging UV sunlight. How does this cream protect from the UV rays of the Sun?

nadezda [96]

It reflects sunlight. It's a physical barrier (in comparison to some sunscreens which are chemical blocks). Sunlight is mostly white light and zinc oxide reflects white light

A sample of gas has its number of molecules quadrupled, its Kelvin temperature doubled, and its volume tripled. By what factor h

steposvetlana [31]

The new pressure changed relative to the original by a factor of 8/3.

<h3>What is the change in the pressure?</h3>

Using the ideal gas equation;

PV = nRT

P = pressure

V = volume

n = number of moles

R = gas constant

T = temperature

P1 = nRT/V

P2 = 4n * R * 2T/3V

Hence;

P2/P1 = 4n * R * 2T/3V ÷ nRT/V

P2/P1 = 4n * R * 2T/3V * V/nRT

P2/P1 =4 * 2/3

= 8/3

In 1911, Ernest Rutherford tested the atomic model existing at the time by shooting a beam of alpha particles (42He, helium nucl

STatiana [176]

Answer:

At the time of Rutherford's experiment, the accepted model for the atom was the Thomson plum-pudding model of the atom, in which the atom consists of a "sphere" of positive charge distributed all over the sphere, with tiny negative particles (the electrons) inside this sphere.

In his experiment, Rutherford shot alpha particles towards a very thin sheet of gold foil. He observed the following things:

1- Most of the alpha particles went undeflected, but

2- Some of them were scattered at very large angles

3- A few of them were even reflected back to their original directions

Observations 2) and 3) were incompatible with Thomson model of the atom: in fact, if this model was true, all the alpha particle should have gone undeflected, or scattered at very small angles. Instead, due to observations 2) and 3), it was clear that:

- The positive charge of the atom was all concentred in a tiny nucleus

- Most of the mass of the atom was also concentrated in the nucleus

So, Rutherford experiment lead to a change in the atomic model of the atom, as it was clear that the plum-pudding model was no longer adequate to describe the results of Rutherford's experiment.

A(n) _____ is a hydrocarbon in which one or more hydrogen atoms is replaced by a -COOH and a -NH^2 group. HELP PLEASE! Please ex

SVETLANKA909090 [29]

That would be an amino acid. The $NH_{2} (amine functional group)$ and -COOH is the functional group for a carboxylic acid hence AMINO ACID.
