PLEASE HELPP MEEE

Physics
1 answer:
Vesnalui [34]3 years ago
7 0

Answer:

B

Explanation:

Newton's 1st law of motion is anything that is at rest remains at rest and anything in motion remains in motion so you will continue to slide until you come into contact with the opposite wall or another force.

The carbon atom with 12 protons and 12 electrons has a charge of:
olga55 [171]

Answer:

Isotopes are the elements having the same atomic number i.e same number of protons which in turn is equal to same number of electrons. Number of protons and electrons are equal as the atom is electrically neutral. So, the only option is A.

I hope it helps you !

A 33.0 g iron rod, initially at 22.7 ∘c, is submerged into an unknown mass of water at 63.3 ∘c, in an insulated container. the f
professor190 [17]
When the iron and the water reach thermal equilibrium, they have same temperature, T=58.5^{\circ}C.
We can consider this as an isolated system, so the heat released by the water is equal to the heat absorbed by the iron.

The hear released by the water is:
Q_w =m_w C_{sw} \Delta T_w
where m_w is the water mass, C_{sw}=4.186 J/(g^{\circ}C) is the specific heat of the water, and \Delta T_w = 63.6^{\circ}-58.5^{\circ}=5.1^{\circ}C is the variation of temperature of the water.

Similarly, the heat absorbed by the iron is:
Q_i = m_i C_{si} \Delta T_i
where m_i = 33.0 g is the iron mass, C_{si}=0.444 J/(g^{\circ}C) is the iron specific heat, and \Delta T_i = 58.5^{\circ}-22.7^{\circ}=35.8^{\circ}C is the variation of temperature of the iron.

Writing Q_w=Q_i and replacing the numbers, we can solve to find mw, the mass of the water:
m_w= \frac{m_i C_{si} \Delta T_i}{C_{sw} \Delta T_w} =24.6 g

What is the resultant fore acting on a 500g object accelerating 5m/s2
zimovet [89]

2.5N

Explanation:

Given parameters:

Mass of object = 500g

Acceleration = 5m/s²

unknown:

Resultant force = ?

Solution:

According to Newton's second law "the net force on a body or the resultant force is the product of its mass and acceleration".

Resultant or net force = m x  a

where  m is the mass

         a is the acceleration

Now we need to convert the mass to kg

 1000g  = 1kg

 500g  = \frac{500}{1000} = 0.5kg

Therefore;

 Input the parameters:

    Force = 0.5 x 5 = 2.5N

On the decibel scale, a “quiet whisper 1 meter away” is about ____________ decibels,  where a “jackhammer 3 meters away” is ____
prisoha [69]
Looking at decibel scale tables on internet, a "quiet whisper 1 meter away" is generally reported to have a sound intensity of about 20 dB, while a jackhammer 3 meters away produces a sound of about 100 dB of intensity, so option a) could be the correct one.
However, the other options could be considered correct as well, because without knowing the exact sound power produced by the whisper or by the jackhammer it's impossible to calculate the exact sound intensity with precision, and since the values reported in the three options are very similar, all the three of them can be considered as valid.
