Answer:
0.00098 N
Explanation:
The weight of an object is given by:

where
m is the mass of the object
g is the gravitational acceleration on the planet
In this problem, we have:
is the mass of the honeybee
is the acceleration due to gravity
Substituting into the equation, we find:

It depends on which side. Opposites attract, so north and south would attract to each other and collide, while north and north or south and south would go away from eachother.
Answer:
Annual water footprint for a typical American in m3 − 2×365 m3
Explanation:
We need the annual water footprint for a typical American first. Then, if each American was to reduce his or her daily water use by 2 m3, this would mean they would reduce his or her annual water use by 365×2 m3, since there are 365 days in a year, and this is the quantity that one needs to substract from the given annual water footprint for a typical American, also measured in m3.
1.
Answer:
N = 77
Explanation:
1) As we know that Tension in the wire is given as
T = 2000 N
now mass per unit length of the wire is given as


Now fundamental frequency is given as



now highest frequency is given as 10000 Hz
so total harmonics is given as


2.
Answer:
D) 7.14 Hz
Explanation:
As we know that
speed = (frequency)(wavelength)
given that
speed = 400 m/s
wavelength = 28 m
so frequency is given as


now if wavelength is doubled then we will have

new frequency will be


3.
Answer:
Number of nodes = 4
A) 4
Explanation:
Number of nodes = number of harmonics + 1
so here we know that
number of harmonics = 3
Number of nodes = 3 + 1
Number of nodes = 4
4.
Answer:
C) 35.1 Hz
Explanation:
fundamental frequency in an organ pipe closed at one end is given as

here we know that
v = 345 m/s
L = 2.46 m
now we have


5.
Answer:
A) 570
Explanation:
Number of harmonics is given as



6.
Answer:

Explanation:
For fundamental frequency we know that

here we know that


now we have


The gravitational potential energy of the mass in increased approximately by 490 J
Gravitational Potential energy formula is
P=mgh
where mass is given my m= 5 Kg
g is the gravitational force i.e. 9.8 
h is the height above the ground that is given by 10 m
P = 5*9.8*10
P = 490 J
What is gravitational potential energy?
The potential energy that a huge item has in relation to another massive object due to gravity is known as gravitational energy or gravitational potential energy. When two objects descend toward one another, the potential energy associated with the gravitational field is released (transformed into kinetic energy).
