Answer:
B. He should change the lengths of the vectors that point tangent to the circle so that each is the same length.
Explanation:
A uniform circular motion is a motion in a circle where the tangential speed of the object is constant.
In the motion map:
- The arrows pointing towards the centre of the circle represent the centripetal acceleration, and their length represent the magnitude of the acceleration
- The arrows pointing tangential to the circle represent the tangential speed, and their length represent the magnitude of the speed
In this motion map, we see that the length of the vectors pointing tangent to the circle is not constant: this means that the speed is not constant. In order to have a uniform circular motion, the speed must be constant, therefore the lengths of the vectors that point tangent to the circle must be the same.
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:less
Explanation:thats the answer
Answer:
x component 60.85 m
y component 101.031 m
Explanation:
We have given distance r = 118 km
Angle which makes from ground = 58.9°
(a) X component of distance is given by
(b) Y component of distance is given by
These are the x and y component of position vector
