Answer:
current (I)=V/R
current (I)=9.0/56022
so I=1.607×10 in the power of negative four Amperes (A)
Answer:
The distance is 19.58 m.
Explanation:
Given that,
Mass = 3.0 kg
Radius = 1.3 m
Angular speed = 6.8 rad/s
Angle = 24°
Acceleration of gravity = 9.81 m/s²
We need to calculate the distance
Using formula of kinetic energy
Total Initial kinetic energy,
....(I)
Now, Total potential energy
....(II)
Equating equation (I) and (II)
Hence, The distance is 19.58 m.

The isomerization of cis-but-2-ene to trans-but-2-ene requires breaking of the π bond.
The bond energy of a C-C σ bond is 347 kJ/mol.
The bond energy of a C=C double bond (σ + π) is 614 kJ/mol.
So the bond energy of a π bond is (614 – 347) kJ/mol = 267 kJ/mol =
267 000 J/mol.
Answer:
0.99 s
Explanation:
The period of a simple pendulum is given by:
where
L is the length of the pendulum
g is the acceleration due to gravity
In this problem, we have
Substituting into the equation, we find the period:
