Answer:
Magnitude of C=
Angle=arctan(Ay+By/Ax+Bx)
Explanation:
Let
A = Axi + Ayj
B = Bxi + Byj
where i and j are unit vectors in the direction of x and y axes respectively.
C=A+B
C = (Ax + Bx)i + (Ay + By)j
The magnitude of vector C can be calculated by adding the square of magnitude of its componets and then taking sqaure root.
Magnitude of C=
And the angle will be
Angle=arctan(Ay+By/Ax+Bx)
Answer:Test variable (independent variable): the land of the 6 locations
Outcome variable (dependent variable): the location
Answer:
The mass of the star would be
Explanation:
From the question we are told that
The angular speed is
The radius of the star is
Generally the minimum mass of the start is mathematically evaluated as
Where is the gravitational constant with a values of
Answer:
Final velocity will be 6.566 m/sec
Explanation:
We have given distance s = 7.76 m
Initial speed u = 3.07 m/sec
Let m be the mass of the scallerer
Force acing down the ramp is the sinθ component of the force due to gravity and this = mg
Acceleration down the ramp =
Speed at the bottom of the ramp can be found out using,
According to third equation of motion
So
v = 6.566 m/sec
Answer:
Heat is transferred directly from one particle of matter to another by the process of conduction.
A circular flow of warmer fluid and cooler fluid is called convection
Heat is always transferred from conduction to radiation
radiation is the transfer of energy by electromagnetic waves.
Heat that is transferred by the movement of currents within a fluid is called conduction
The only form of heat transfer that does not require matter is specific heat
Water bubbles up through a hot spring at Yellowstone National Park. What method of heat transfer is this?
convection

I hope that this helps, I kinda rushed on it
