Answer:
6.93 volts
Explanation:
q = magnitude of charge on proton = 1.6 x 10⁻¹⁹ C
r = radius of the orbit = 2.08 x 10⁻¹⁰ m
V = Electric potential due to proton on electron
Electric potential due to proton on electron is given as
Inserting the values
V = 6.93 volts
Answer:
F=2.589×10⁻⁷ Newtons
Explanation:
The gravitational force of attraction between two bodies is given by
F= Gm₁m₂/r²
Where m₁ and m₂ are the masses of the two bodies, G is the universal gravitational constant while r is the distance between the two bodies.
G=6.67408 × 10⁻¹¹m³kg⁻¹s⁻²
r=1.15m
m₁=75.0kg
m₂=68.4kg
Therefore F= (6.67408×10⁻¹¹m³kg⁻¹s⁻²×75.0kg×68.4kg)/(1.15m)²
F=2.589×10⁻⁷ Newtons
A material that is malleable and conducts electricity is
most likely is a metal. The answer is letter C.
The physical property that makes wax good for making
sculpture molds is the melting point. The answer is letter D.
Filtration can be used to separate mixtures based on the
size of their particles. The answer is letter D.
Answer:
υ = 345.82 m/s
Explanation:
The formula used to find the speed of sound in air, at different temperatures is given as follows:
where,
υ = speed of sound at given temperature = ?
υ₀ = speed of sound at 0°C = 331 m/s
T = temperature in K = 15°C + 273 = 298 k
Therefore, using these values in the equation, we get:
<u>υ = 345.82 m/s</u>
The answer would be
C. Rods and Cones
