Answer:
La longitud del camino recorrido es de 25.9 [m]
Explanation:
Se reemplaza el valor de tiempo en segundos en la ecuación dada de desplazamiento
x=10+20*(3) - 4.9*(3)^2
x= 25.9 [metros]
Answer:
The correct order is (b), (a), (d), (c).
Explanation:
Given:
Correct order is as follows,
(b) White light with all colors is emitted by the sun.
(a) White light interacts with molecules in the atmosphere.
(d) When interacting with molecules, blue light with shorter wavelength scatters more in all direction.
(c) Light that is primarily blue comes from all directions in the sky.
Therefore, the correct order is (b), (a), (d), (c).
Answer:
Use the range formula - R = V^2 sin 2θ / g
A: R = V^2 sin 80 / g = .985 V^2 / g
B: R = V^2 sin 100 / g = .985 V^2 / g
Answer:
Temperature of neon gas = 875 K
Explanation:
Using Ideal gas equation as:
PV=nRT
Where,
P is the pressure of the gas
V is the volume of the gas
n is the number of moles
R is the gas constant
T is the temperature
Also,
The ideal gas equation can be written as:
Thus,
As Density and Pressure is constant , We only consider molar mass and Temperature which are directly proportional according to the equation above as:
Data given for He:
Temperature (T₁) = 175 K
Molar mass of He (M₁)= 4 g/mol
For Ne:
Temperature (T₂)= ?
Molar mass of He (M₂)= 20 g/mol
Applying in the equation,
<u>Temperature of neon gas = 875 K</u>
Answer:
The angle wires have to be placed to experience full force is such that the angle between the direction of current flow and the direction of the magnetic field is 90°
Explanation:
The direction of the force acting on a conductor through which a charge flows is given by Flemings Left Hand Rule which states that the direction of the force acting on a conductor carrying a current of charge is perpendicular to both the direction in which the current is flowing and the direction of the magnetic field
Therefore, wires carrying flowing charges has to be placed such that the direction of charge (current) flow is perpendicular (at 90°) to an existing magnetic field to experience (maximum) full force
