The value is
Explanation:
From the question we are told that
The velocity which the rover is suppose to land with is
The mass of the rover and the parachute is
The drag coefficient is
The atmospheric density of Earth is
The acceleration due to gravity in Mars is
Generally the Mars atmosphere density is mathematically represented as
=>
=>
Generally the drag force on the rover and the parachute is mathematically represented as
=>
=>
Gnerally this drag force is mathematically represented as
Here A is the frontal area
So
=>
=>
Answer:
Na20
Explanation:
Compound having oppositely charged ions are considered as ionic compounds.
Ionic compounds are formed when complete transfer of electrons takes place between the atoms forming a bond. This bond is formed between a metal and a non-metal or a polyatomic cation and an non-metal or a metal and a polyatomic anion. For Example: etc..
Covalent compounds are formed when sharing of electrons takes place between the atoms forming a bond. This bond is formed between two non-metals. For Example: etc..

Answer: 0.001m^3
Explanation:
Given the following :
Mass of tub = 0.650kg
Mass of rock = 0.350kg
In this scenario:
Upthrust is the weight of fluid displaced
Upthrust = Total weight of tub (since the tub floats, and top of tub is level with the water line )
Recall Weight = mass * acceleration due to gravity(g)
g = 9.8m/s
Total mass = (0.650 + 0.350)kg = 1kg
Weight = 1kg × 9.8m/s = 9.8N
Upthrust = 9.8N
Recall: Upthrust = Density × acceleration due to gravity(g)× displaced body volume of fluid
Density of water = 1000kg/m^3
g = 9.8m/s^2
9.8N = 1000 × 9.8 × Volume
9.8 = 9800V
V = 9.8 / 9800
V = 0.001m^3
Answer:
So average speed of the earth in miles per hour will be equal to
Explanation:
We have given average speed of the earth v = 29783 km/sec
We have to convert this speed into miles per hour
For converting the speed in miles per hour first we have to convert km to miles and sec to hour
As we know that 1 km = 0.6213 miles
And 1 sec = 0.000277 hour
So
So average speed of the earth in miles per hour will be equal to
Answer:
Internal hardware is physical parts that help the computer work; software is the programs and applications that make the computer work.
Explanation:
I don't really have an explanation on how this was right. But it was a lucky guess that ended up being correct!
