Gases expand to fill all the space available. Their particles fly all over the place, and they take the shape and volume of whatever you put them in.
Answer:
3.76 N
Explanation:
We are given that two force vectors point in opposite directions.
Let
![\mid F_1\mid=7.29N](https://tex.z-dn.net/?f=%5Cmid%20F_1%5Cmid%3D7.29N)
![\mid F_2\mid=-3.53](https://tex.z-dn.net/?f=%5Cmid%20F_2%5Cmid%3D-3.53)
Because second force act in opposite direction.
We have to find the magnitude of sum of two forces.
We know that triangle law of addition
Resultant sum=![\mid F_1\mid+\mid F_2\mid](https://tex.z-dn.net/?f=%5Cmid%20F_1%5Cmid%2B%5Cmid%20F_2%5Cmid)
Substitute the values then we get
Resultant sum of two forces=![7.29-3.53](https://tex.z-dn.net/?f=7.29-3.53)
Resultant sum of two forces=3.76 N
Hence, the magnitude of sum of two forces=3.76 N
Yes physics do involve cheerleading . Physics are found in every single motion and stunt
Answer:
Increased by 16 times
Explanation:
F = Gravitational force between two bodies
G = Gravitational constant = 6.67408 × 10⁻¹¹ m³/kg s²
m₁ = Mass of one body
m₂ = Mass of other body
d = distance between the two bodies
![F=\frac{Gm_1m_2}{d^2}\\ F=\frac{1}{d^2}\quad \text {(as G and masses are constant)}](https://tex.z-dn.net/?f=F%3D%5Cfrac%7BGm_1m_2%7D%7Bd%5E2%7D%5C%5C%20F%3D%5Cfrac%7B1%7D%7Bd%5E2%7D%5Cquad%20%5Ctext%20%7B%28as%20G%20and%20masses%20are%20constant%29%7D)
![F_{new}=\frac{1}{\left (\frac{d}{4}\right )^2}\\\Rightarrow F_{new}=\frac{1}{\frac{d^2}{16}}\\\Rightarrow F_{new}={16}\times \frac{1}{d^2}\\\Rightarrow F_{new}=16\times F](https://tex.z-dn.net/?f=F_%7Bnew%7D%3D%5Cfrac%7B1%7D%7B%5Cleft%20%28%5Cfrac%7Bd%7D%7B4%7D%5Cright%20%29%5E2%7D%5C%5C%5CRightarrow%20F_%7Bnew%7D%3D%5Cfrac%7B1%7D%7B%5Cfrac%7Bd%5E2%7D%7B16%7D%7D%5C%5C%5CRightarrow%20F_%7Bnew%7D%3D%7B16%7D%5Ctimes%20%5Cfrac%7B1%7D%7Bd%5E2%7D%5C%5C%5CRightarrow%20F_%7Bnew%7D%3D16%5Ctimes%20F)
∴Force will increase 16 times
The only condition under which a concave mirror forms a virtual and upright image on the principal axis is when there is a concave mirror with the object in front of the focal point. This is the only positioning available for the said image to be formed.
