Answer:
the equations of motion can be separated into an equation that depends on a single variable.
Explanation:
he one-dimensional kinematics equations can be applied to two-dimensional systems because we can write the equations in such a way that each one of them depends on variables in a single dimension plus time, which, because it is a scalar, can be used in all dimensions.
A mathematical way of saying this is that the equations of motion can be separated into an equation that depends on a single variable.
Answer:
Explanation:
According to newton's law , force between mass m₁ and m₂ at distance x is given by the following expression
F = G m₁m₂ / x²
differentiating F with respect to x , we have
dF / d x = ₋2G m₁m₂ / x³ .
Rate of reduction of force ∝ 1 / x³
Given that,
Deacelectration = -15 m/s²
Negative sign shows the declaration
Slowly speed = 25 m/s
Acceleration = 35 m/s²
Speed = 170 m/s
We need to calculate the time
Using equation of motion
Where, v = final velocity
u = initial velocity
a = acceleration
t = time
Put the value into the formula
We need to calculate the distance from the original runway
Using equation of motion
Hence, The distance from the original runway is 48.2 m.
Answer:
The increase in thermal energy results in an increase in pressure.
Explanation:
- The increase in entropy is directly related to the increase in temperature. So the thermal energy in heat engine increases the temperature of that surrounding.
- Higher temperature means the kinetic energy of particles is also higher, their vibration is increasing. So it increases the pressure (ideal gas law).
- In this way the increment in the thermal energy in heat engine moves piston by increasing the pressure.
