Answer:
114.075 N
798.525 Nm
Explanation:
C = Drag coefficient = 0.5
ρ = Density of air = 1.2 kg/m³
A = Surface area = 9 m²
v = Velocity of wind = 6.5 m/s
r = Height of the tree = 7 m
Drag equation
Magnitude of the drag force of the wind on the canopy is 114.075 N
Toque is given by the product of force and radius
Torque exerted on the tree, measured about the point where the trunk meets the ground is 798.525 Nm
Explanation: Vesta is second largest object in the asteroid belt after dwarf planet Ceres. Basalt which is found on Vesta which is very unusual to be found on an asteroid. Its presence indicate the volcanic activity at some point in Vesta's distant past. Basalt is a fine-grained igneous rock. It is formed when bits of lava shoot out of volcanoes.
Answer:
- <u><em>Option A) A gas was produced.</em></u>
Explanation:
Indeed, the production of a gas is an indication that a new substance was produced as result of the reaction of the matter that constitutes the antiacid tablet and the distilled water.
A chemical reaction is a change that yields the formation of new substances (products), due to the rearrangements of the atoms of the reactants.
In a very simple form, you can represent a chemical reaction by the general equation:
Which means that some elements or compounds, those in the reactant side of the equation, undergo a change in which some chemical bonds are broken, the atoms separate from the original substances and combine into a new arrangement in which they form one or more different substances (products).
The option B), that the table dissapeared is not a clear evidence of a chemical change because it could have been dissolved, which is a physical change.
Also, the option C), that there was a color change, cannot be cited as an evidence of a chemical reaction, since the color is a physical property.
As for the option D, that there was a change in mass, is not a viable option, since mass cannot change either with a chemical or physical change.
Answer:
The weight of the atmosphere decreases along with the pressure. The pressure within the balloon would eventually be too much to handle that the balloon would pop since the air around it no longer as about/more pressure.
We know that:
p=mv
p=89kg*9m/s
p=801Ns
