Question 5
1 / 1 pts
True
False
Yes, linear momentum
L
is the product of mass and velocity (given by m
V
). Since m is a positive scalar
quantity,
L
has the same direction as
V
.
Question 6
1 / 1 pts
Only the externally applied forces
The forces that have larger magnitudes.
Internal forces.
Both internal and externally applied forces.
Internal forces don't appear in the summation since they occur in equal and opposite collinear pairs, and
therefore they cancel out.
A particle's linear momentum is a vector quantity and has same direction as the particle's
velocity.
The ±gure shows a system of particles moving relative to an inertial reference frame. The forces acting on
some of the particles are shown in the ±gure. Externally applied forces are represented by upper case F
and internal forces are represented by lower case f
letters. The principle of linear impulse and momentum

You are currently in a stable orbit 9000 km
(1km=1000m) from the center of planet Proxima
Centauri B.
According to the calculations done by NASA, Planet Proxima Centauri B has
a mass of approximately 7.6x10^24kg.
Based on fuel consumption and expected material aboard the ship, your
colony ship lander has a mass of approximately 1.1x10^5 kg.
1. Using Newton's Law of Universal Gravitation, determine what the force of
gravity on your ship at that orbit be using the early measurements
2.Using Newton's second law determine the acceleration of your lander due
to gravity
3.Upon arrival, you measure the actual force of gravity to be 6x10^5 N,which

A cylindrical fuel rod (k = 30 W/m K) of 2 cm in diameter is encased in a concentric tube and cooled by water. The fuel rod
generates heat uniformly at a rate of 100 MW/m3, and the average temperature of the cooling water is 80°C with a
convection heat transfer coefficient of 2500 W/m2-K. The operating pressure of the cooling water is such that the surface
temperature of the fuel rod must be kept below 200°C to avoid the cooling water from reaching the critical heat flux (CHF).
The crițical heat flux is a thermal limit at whichr a boiling crisis can occur that cause overheating on the fuel rod surface and
lead to damage.

The moment of inertia of a helicopter's rotor is 320kg. m². The rotor starts from rest
and at t = 0, the pilot begins by advancing the throttle so that the torque exerted on
the rotor by the engine (in N.m) is modelled by as a function of time (in seconds) by
T = 250t.
a) How long does it take the rotor to turn ten revolutions?
b) What is the rotor's angular velocity (in RPM) when it has turned ten

According to the calculations done by NASA, Planet Proxima Centauri B has a mass of approximately 7.6x10^24kg. Based on fuel consumption and expected material aboard the ship, your colony ship lander has a mass of approximately 1.1x10^5 kg. 1. Using Newton's Law of Universal Gravitation, determine what the force of gravity on your ship at that orbit be using the early measurements 2.Using Newton's second law determine the acceleration of your lander due to gravity 3.Upon arrival, you measure the actual force of gravity to be 6x10^5 N,which ic difforent from vourcalclated vauein cuection 1 ldentify 2cnocific e to searcharrow_forwardYou are watching a live concert.
