Answer:
true
Explanation:
if you apply force to the top of a square it will not move
Answer:
N = 3.54 * 10²³ atoms
Explanation:
The formula to apply here is the idea gas law;
PV = nRT where ;
P= pressure of the gas= 1.013 * 10⁵ Pa
V= volume of the gas = 4/3 * 3.14 *0.15³= 0.01414 m³
n= amount of a substance = ?
R= ideal gas constant= 8.314
T= temperature= 293 K
Applying the values to the formula;
PV = nRT
1.013 * 10⁵ * 0.01414 = n * 8.314*293
n= 1.013 * 10⁵ * 0.01414 / 8.314*293
n= 0.588 moles
1 mole = 6.022 * 10²⁷ atoms/ mole
0.588 moles = 0.588 * 6.022 * 10²⁷
N = 3.54 * 10²³ atoms
This is conservation of momentum. At the beginning the total momentum is zero. When you throw the stone you give the stone a positive momentum, which means you must have a negative momentum (when I say negative I mean in the opposite direction of the direction of the stone) so that the total momentum is still zero. You and the canoe will move in the opposite direction of which you threw the stone.
Answer:
Explanation:
Given:
Gravity of Mars = 0.38 times the gravity at Earth
Gravity of Earth is, 
Radius of Mars (R) = 3400 km
Mass of mars (M) = ?
We know that, the acceleration due to gravity of a planet of mass 'M' and radius 'R' is given as:
Now, as per question:
Plug in 9.8 for 
and solve for 
. This gives,
Now, plug in this value in the above equation and solve for 'M'. This gives,
Therefore, the mass of Mars is .
