Answer: The net force is negative, The net force is positive, There is change in motion.
When an balanced force acts, there is change in motion. In case of balanced forces, the object does not change its motion. The unbalanced force causes change in the momentum of the object. There would be some net force. It would not be zero. The net force is zero when the acting forces are balanced. The net force in case of unbalanced forces have certain magnitude and are positive or negative depending on the direction. The positive and negative sign denotes direction of the net force.
Answer:
It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. ... The momentum of a body is equal to the product of its mass and its velocity.
A nation's nominal GDP is $1.5 trillion with an inflation rate of 5%. ∴ Real GDP is 30 trillion.
<u>Explanation:</u>
Key Terms
GDP deflator: A measure of the level of prices of all new, domestically produced, final goods and services in an economy. It is calculated by computing the ratio of nominal GDP to the real measure of GDP.
real GDP: A macroeconomic measure of the value of the economy’s output adjusted for price changes (inflation or deflation).
nominal GDP: A macroeconomic measure of the value of the economy’s output that is not adjusted for inflation.
GDP deflator( inflation rate = 5% ) =
Inflation rate =
trillion
∴ Real GDP is 30 trillion.
Answer
given,
mass of disk = 2 Kg
radius = 0.1 m
time = 10 sec
a) 800 rpm to rad/s
=
=
b) 740 rpm to rad/s
=
=
c) Angular acceleration
d) moment of inertia of disc
I = 0.01 Kg.m²
e) τ = I α
τ = 0.01 x 0.629
τ = 6.29 x 10⁻³ N.m
f) impulse = Force x time
J = 0.629 Ns
g) Work done
W = Δ KE
W = 5.07 J
Urinary → kidneys
Integumentary → skin, sweat, glands
Respiratory → lungs
Digestive → intestines
Circulatory → Blood that circulates through the body passes through one of the two kidneys where it is filtered!
So your answer is : D)
There you go! I really hope this helped, if there’s anything just let me know! ☻
