Answer:
The speed of electron is and the speed of proton is 2468.02 m/s.
Explanation:
Given that,
Electric field, E = 560 N/C
To find,
The speed of each particle (electrons and proton) 46.0 ns after being released.
Solution,
For electron,
The electric force is given by :
Let v is the speed of electron. It can be calculated using first equation of motion as :
u = 0 (at rest)
For proton,
The electric force is given by :
Let v is the speed of electron. It can be calculated using first equation of motion as :
u = 0 (at rest)
So, the speed of electron is and the speed of proton is 2468.02 m/s. Therefore, this is the required solution.

Answer:
I1 < I2
V1 > V2
Explanation:
Let the EMF of both the batteries is E and the internal resistance of both the cells is r.
The relation between the current and the EMF is given by
where, R be the resistance connected in the circuit.
the relation between the terminal potential difference and the EMF is given by
V = E - Ir
where, V is the terminal potential difference
If R1 is connected,
The current is given by
.... (1)
The terminal potential difference is given by
..... (2)
If R2 is connected,
The current is given by
.... (3)
The terminal potential difference is given by
..... (4)
As given in the question, R2 > R1
So, by the equation (1) and (3), we get
I1 < I2
and by the equation (2) and (4) ,we get
V1 > V2
Answer:
Amine have higher boiling points than hydrocarbons.
Explanation:
Primary, secondary and tertiary amines have higher boiling points than hydrocarbons because they can engage in intermolecular hydrogen bonding.
Amines has three classes
1. Primary amines
2. Secondary amines
3. Tertiary amines
All this classes of amines have higher boiling point than hydrocarbons due to C-N bond in them
This is because amines can engage in hydrogen bonding with water, amines of low molar mass are quite soluble in water.
Amines are having higher boiling points than hydrocarbons, as C-N bond in amines is more polar than a C-C bond in hydrocarbons. Due to the polar nature of amines, it forms intermolecular H-bonds and exists as associated molecules.
Answer: In SI units, G has the value 6.67 × 10-11 Newtons kg-2 m2. The direction of the force is in a straight line between the two bodies and is attractive. Thus, an apple falls from a tree because it feels the gravitational force of the Earth and is therefore subject to “gravity”.
