We know that AD is the shortest way but ABCD is connected in series
Equivalent Resistance =R1+R2+R3
=(10+10+10)ohm
=30ohm
Since BC and AD is connected in parallel
1/Req=1/R1 + 1/R2
=1/30 + 1/10
=3+1/30
=4/30
So, Req=30/4 ohm
Now,Current drawn from the battery
=> I = V/R
=> I = 30/4 ohm/3v
=> I = 30/4*3
So, I = 10/4 A

<u>Answer:</u> The molar mass of metal (M) is 47.86 g/mol
<u>Explanation:</u>
Let the atomic mass of metal (M) be x
Atomic mass of
To calculate the mass of metal, we use the equation:
Mass percent of metal = 59.93 %
Mass of metal = x g/mol
Mass of metal oxide = (x + 32) g/mol
Putting values in above equation, we get:
Hence, the molar mass of metal (M) is 47.86 g/mol

Answer:
Explanation:
a) ωp = 2π radians / 1.7 s = <u>3.7 rad/s</u>
b) ωs = 3.7 rad/s(9.5 cm / 4.5 cm) = 7.8 rad/s
v = (ωs)R = 7.8(65) = 507 cm/s or <u>5.1 m/s</u>
c) ωs = 3.5 m/s / 0.65 m = 5.38 rad/s
ωp = 5.38(4.5 cm / 9.5 cm) = 2.55 rad/s
t = θ/ω = 2π / 2.55 = 2.463... <u>2.5 s</u>
Answer:
2.) Use a wrench with a longer handle.
Explanation:
It is suggested to use a wrench with longer handle if you cannot exert enough force to loosen a bolt with a wrench.
In doing this work, the torque which is the force that can turn the screw is not enough;
Torque = force x distance
If we increase the distance or the length of the handle, we can generate more torque to overcome the force needed.
