Answer:
Atoms can be joined together by chemical bonds.
Explanation:
When atoms form bonds, they can achieve a stable electron arrangement. To achieve a stable electron arrangement atoms can lose, gain or share electrons. There are many different types of bonds that hold atoms together.
Answer:
on increasing pressure, temperature will also increase.
Explanation:
Considering the ideal gas equation as:
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Thus, at constant volume and number of moles, Pressure of the gas is directly proportional to the temperature of the gas.
P ∝ T
Also,
Also, using Gay-Lussac's law,
Thus, on increasing pressure, temperature will also increase.
Answer:We can solve this using the Law of Conservation of Momentum. If both marbles are in our system, the initial momentum should equal the final momentum.
The initial momentum can be solved for as so:
* + =
(0.06)(0.7) + (0.03)(0) = 0.042 [kg * m/s]
So if the system has an initial momentum of 0.042, it should have the same final momentum.
(0.06)(-0.2) + (0.03)() = 0.042
(0.03)() = 0.54
() = 18 [m/s]

Answer:
Explanation:
Magnitude of magnetic field due to a current carrying conductor
= ( μ₀ / 4π ) x 2I / d , I is current , d is distance from wire . This formula has been derived from Ampere's Law.
= 10⁻⁷ x 2 x 23 / 10 Current given I = 23
= 46 x 10⁻⁸ T .
Magnetic field due to current 17 A
10⁻⁷ x 2 x 17 / 10
= 34 x 10⁻⁸ T .
Magnetic field due to current 11 A
10⁻⁷ x 2 x 11 / 10
= 22 x 10⁻⁸ T .
magnetic field due to current 17 A and 11 A are in same direction so total magnetic field
= 34 x 10⁻⁸ + 22 x 10⁻⁸
= 56 x 10⁻⁸ T
magnetic field due to current 23 A in opposite direction so total magnetic field
= 46 x 10⁻⁸ - 56 x 10⁻⁸
= - 10 x 10⁻⁸ T
Magnitude = 10 x 10⁻⁸ T .
