Answer:
Explanation:
According to Newton's Second Law of Motion, force is the product of mass and acceleration.
The net force is 5 Newtons and the mass is 13 kilograms. Let's convert the units for force to make the problem and unit cancellation easier.
- 1 Newton (N) is equal to 1 kilogram meter per square second (1 kg*m/s²)
- The net force of 5 N is equal to 5 kg*m/s²
Now we know the values for 2 variables:
Substitute the values into the formula.
Since we are solving for the accleration we must isolate the variable, a. It is being multiplied by 13 kilograms and the inverse of multiplication is division. Divide both sides by 13 kg
The units of kilograms (kg) cancel.
The original measurements of force and mass ( 5 and 13) have 1 and 2 significant figures. We must round our answer to the least number of sig figs: 1.
For the number we found, that is the tenths place. The 8 in the hundredth place (0.384615385) tells us to round the 3 up to a 4.
The acceleration is approximately <u>0.4 meters per square second.</u>
<u>Answer:
</u>
Earth convection occurs at the mantle layer
<u>Explanation:
</u>
The movement of less dense material above the more dense material is called as convection. The mantle is the layer that lies between the core and the crust of the earth. The mantle is composed of rocks containing silicon, magnesium, oxygen, aluminium, iron and other minerals.
The heat energy of the core is transmitted to the rock in the lower mantle. This makes the rock with less temperature that lies in upper mantle to move down slowly. Now the rocks that are pushed up is eventually cooled and again pushed down by the hotter rock from the lower mantle. This is called as convection in earth’s mantle .
To find the x component use the following formula, where Ф = theta = the angle 'a' makes with the x axis.
Answer:
the spear will end up above the fish relative to the actual position of the fish.
Explanation:
due to refraction of light coming from the fish the fish will appear slightly above from its real position
So due to this refraction the spearfisher will throw the spear directly at the image of the fish due to which it will not reach the position of fish but it will reach the position above the fish.
So here we can say that the spear will end up above the fish relative to the actual position of the fish
Answer:
The value is
Explanation:
From the question we are told that
The atmospheric temperature is
The molar mass of carbon dioxide is
The pressure is
The number of moles is
Generally the translational kinetic energy is mathematically represented as
Here R is the gas constant with value
Generally the degree of freedom of carbon dioxide in terms of translational motion is f = 3
So
=>
