Given:
g =? m/s2
m = 2.2 kg
w = 19.6 N
Equation: g = w/m
g = 19.6 N/2.2 kg
<span>g = 8.9 m/s2</span>
Comets are divided into two types. Long-period comets are the comets that take more than two hundred years to finish an orbit throughout the Sun originate from the Oort Cloud.
<u>Explanation:</u>
- The Oort Cloud has sufficient distance apart of the Sun than the Kuiper Belt, it seems that the Oort Cloud objects were made closer to the Sun than the Kuiper Belt things.
- Long-period comets have highly eccentric orbits.
- The Oort cloud is considered to own a large range commencing from among 2,000 and 5,000 AU to 50,000 AU.
- The chemical makeup of long-period and short-period comets is quite alike.
Answer:
D: When one bulb burns out, all the other lights stay on
Explanation:
In series combination of light bulbs same current must flow through all the bulbs and hence if one bulb is burn out then current through all bulbs tripped to zero and all bulbs will turn off.
Now in parallel combination all bulbs are connected parallel to the source of energy due to which the bulbs will remain in circuit if any one bulb is burn out.
So here if we used combined circuit of the bulbs i.e. parallel then in that case if one of the bulb is burn out then it must show that rest of the other bulbs must glow.
so here correct answer would be
D: When one bulb burns out, all the other lights stay on
The coefficient of kinetic friction between the block and the incline is 0.168.
<h3>
Coefficient of kinetic friction</h3>
The coefficient of kinetic friction is determined from the principle of conservation of energy as follows;
distance traveled on the incline = L
L = h/sin35
L = 1.743 h
Since it takes twice the time travel down,
velocity to slide = 1.743 h/2t = 0.871 v
- v is the velocity to drop from the vertical height
K.E of the block when it slides = ¹/₂mv₁² = ¹/₂m(0.871v)² = 0.871²(K.E to fall) = 0.758K.E to fall straight down
<h3>Energy lost to friction</h3>
1 - 0.758 = 0.24
<h3>Conservation of energy</h3>
μmgcos(35) = 0.24(mgsin(35)
μcos(35) = 0.24(sin(35)
μ = 0.168
