Answer:
100 N
Explanation:
Given that,
Two forces whose resultant is 100newton are perpendicular to each other.
If one of them makes an angle of 60newton with the resultant.
and
The magnitude of force,
or
F = 100 N
So, the magnitude of force is 100 N.
Answer:
Explanation:
As we know that the radius of the circular motion is given as
time period of the motion is given as
now we know that it is moving with uniform speed
so it is given as
now plug in all data
Answer:
The value is
Explanation:
From the question we are told that
The molar mass of hydrazine is
The initial temperature is
The final temperature is
The specific heat capacity is
The power available is
The mass of the fuel is
Generally the number of moles of hydrazine present is
=>
=>
Generally the quantity of heat energy needed is mathematically represented as
=>
=>
Generally the time taken is mathematically represented as
=>
=> t = 2480505.6377 s
Converting to hours
=>
Answer:
Explanation:
To find the direction of this vector we need o find the angle that has a tangent of the y-component over the x-component:
but since we are in Q2 we have to add 180 degrees to that angle giving us 165.5 degrees
