The particles will move faster due to the increased energy from the heat.
Answer:
Explanation:
<u>Net Force
</u>
According to the second Newton's law, the net force exerted by an external agent on an object of mass m is:
Fn = m.a
Where a is the acceleration of the object. The net force is the sum of the individual vector forces applied to the object.
The m=1500 Kg car has two horizontal forces applied: the forward force of 5000 N that causes the movement and the air resistance force of 1250 N that opposes motion.
The net force is Fn = 5000 N - 1500 N = 3500 N
To find the acceleration, we solve the equation for a:
The car's acceleration is
Answer:
observed frequency = 109.68 Hz
Explanation:
given data
speed u = 20.9 m/s
frequency f = 103 Hz
solution
we consider here speed of sound (v) is 343 m/s
so observed frequency is express as
observed frequency = f × ...............1
put here value and we get
observed frequency = 103 × \frac{343}{343-20.9}
observed frequency = 109.68 Hz
Answer:
Diabetic Retinopathy is a form of diabetes that affects the eyes. It can be caused by damage to the retinas, and can cause permanent damage to the eyes, and even blindness. Initially the patient is asymptomatic and become more visibly affected in later stages. It can be treated if caught early, or in mild cases.
