Answer:
Explanation:
given data:
Q = - 2.1 Btu
![V_2 = V_1 [\frac{P_1}{P_2}]^{1.1}](https://tex.z-dn.net/?f=V_2%20%3D%20V_1%20%5B%5Cfrac%7BP_1%7D%7BP_2%7D%5D%5E%7B1.1%7D)
![= 1 [\frac{23040}{56160}]^{\frac{1}{1.1}](https://tex.z-dn.net/?f=%3D%20%201%20%5B%5Cfrac%7B23040%7D%7B56160%7D%5D%5E%7B%5Cfrac%7B1%7D%7B1.1%7D)
work done during polytropic process
= -18442.1 ft lbf
we know 1 Btu = 778.169 ft. lbf, therefore
w = -23.6993 Btu
Answer:
The offspring is homozygous for eye color
Explanation: I had this question on my test and this was the answer, i hope this helps :)
Answer:
The tendency of undisturbed objects to stay at rest or to keep moving with the same velocity is called inertia. This is why, the first law of motion is also known as the law of inertia.
<em><u>Example</u></em><em><u>.: A ball at rest on the ground continues to be at rest unless someone kicks it or any external force acts on it.</u></em>

Answer:
a) 0.3 m
b) r = 0.45 m
Explanation:
given,
q₁ = 0.44 n C and q₂ = 11.0 n C
assume the distance be r from q₁ where the electric field is zero.
distance of point from q₂ be equal to 1.8 -r
now,
E₁ = E₂
1.8 = 6 r
r = 0.3 m
<h3>b) zero when one charge is negative.</h3>
let us assume q₁ be negative so, distance from q₁ be r
from charge q₂ the distance of the point be 1.8 +r
now,
E₁ = E₂
1.8 =4 r
r = 0.45 m
The correct answer to the question is : D) Impulse
EXPLANATION:
Before going to answer this question, first we have to understand impulse.
Impulse of a body is defined as change in momentum or the product of force with time.
Mathematically impulse = F × t = m ( v - u ).
Here, v is the final velocity
u is the initial velocity
F is the force acting on the body for time t.
Hence, the perfect answer of this question is impulse m i.e the force multiplied with time is known as impulse.
