Answer:
Wavelength = 0.66 meters
Explanation:
Given the following data;
Speed = 330 m/s
Frequency = 500 Hz
To find the wavelength;
Mathematically, wavelength is calculated using this formula;
Substituting into the equation, we have;
Wavelength = 0.66 meters

partial pressure in a mixture of two or more gases will be given by formula
= mole fraction of gas * total pressure
now here mole fraction is same as percentage of gas in the mixture
Now mole fraction of oxygen is 0.20095 (20.095%)
now here pressure of oxygen in the mixture is given as
so pressure due to oxygen in the mixture will be 0.342 atm
Answer:
20.095
Explanation:
Given:-
Speed = 36 km/hr
converting speed into m/s
Speed = 36*5/18
Speed = 10 m/s
t = 10 sec
By using the Formula
Distance = Speed * time
D = 10*10
D = 100 m

Answer:
the magnitude of the ball's acceleration as it comes to rest on the foam is 817.5 m/s²
Explanation:
Given the data in the question;
initial velocity; u = 0 m/s
height; h = 2.5 m
we find the velocity of the ball just before it touches the foam.
using the equation of motion;
v² = u² + 2gh
we know that acceleration due gravity g = 9.81 m/s²
so we substitute
v² = ( 0 )² + ( 2 × 9.81 × 2.5 )
v² = 49.05
v = √49.05
v = 7.00357 m/s
Now as the ball touches the foam
final velocity v₀ = 0 m/s
compresses S = 3 cm = 0.03 m
so
v₀² = v² + 2as
we substitute
( 0 )² = 49.05 + 0.06a
0.06a = -49.05
a = -49.05 / 0.06
a = -817.5 m/s²
Therefore, the magnitude of the ball's acceleration as it comes to rest on the foam is 817.5 m/s²
Answer:
d = 3.44 x 10⁸ m
Explanation:
The minimum distance required will be the distance from the centre of the earth to a point where gravitational intensity due to both earth and moon becomes equal . Once this point is reached , moon will attract the baseball on its own .
Let this distance be d from the centre of the earth
So GM / d² = G m / ( 3.82 x 10⁸ - d )²
M is mass of the earth , m is mass of the moon
M / m = ( d / 3.82 x 10⁸ - d )²
5.972 x 10²⁴ / 7.34 x 10²² = ( d / 3.82 x 10⁸ - d )²
81.36 = ( d / 3.82 x 10⁸ - d )²
9.02 = d / 3.82 x 10⁸ - d
34.45 x 10⁸ - 9.02 d = d
34.45 x 10⁸ = 10.02 d
d = 3.44 x 10⁸ m
