Answer:
The force of static friction is 17.15 N
Explanation:
It is given that,
Mass of the bucket, m = 5 kg
The coefficient of static friction is, 
We need to find the maximum force of static friction. It is given by :
F = 17.15 N
So, the force of static friction is 17.15 N. Hence, this is the required solution.
Answer:
v2=0.79 m/s
Explanation:
equation of continuity: V1A1=V2A2
A=(pi)r^2
A1=(pi)(0.55cm)^2
A2=(pi)(1.17cm)^2
convert cm2->m2
A1= 0.95cm2=
A2= 4.3cm2=
(3.57 m/s)(0.000095 m^2)=(x m/s)(0.00043 m^2)
v2=0.79 m/s
hope this helped
The correct answer of the question is : A) Orbits a star, B) Gravity makes spherical and D) Clear orbits of other objects.
EXPLANATION :
The classification of a celestial object to be a planet depends on some parameters.
The most important thing about the planet is that it must clear its orbit. It means it won't share its orbit with other planets. Otherwise, it will be considered as a dwarf planet.
The second thing is that it must move around any stars. The star becomes the centre of that solar system around which planets start revolving in different orbits.
The third thing is that planets are approximately spherical in shape.
The size of the planets does not play a crucial role in the classification of planets. Planets may be smaller than mercury also.
Hence, all the options except the third one are suitable.
Answer:
a) The astronauts would see the real length of the meter stick, i.e. L₀
b) The length of the meter stick as measured by the stationary observer will be 
Explanation:
a) Let the proper length of the meter stick be L₀
The meter stick and the astronauts on the on the space ship are on the same moving frame, therefore, they will see the exact length of the meter stick, that is, L₀
b) A stationary observer watching the space ship and meter stick travel past them will see a contracted length of the meter stick
The original length = L₀
Let the speed of the space ship = v
The contracted length, L, is related to the original length in the frame of rest by
L = L₀/γ......................(1)
Where γ = 
....................(2)
Substituting equation (2) into (1)
Answer:
Hello your question is vague hence I will provide a general answer on the importance of : Waste reduction, rationalization of consumption, reuse, recycling as ways of preserving the natural resources
answer :
Waste reduction : when we reduce the amount of wastage on items we use especially items produced from natural raw materials we will help preserve the natural resource because they can be used to produce varieties of other items
Reuse and recycling of waste products help keep our natural environment healthy thus preserving our natural resources.
Explanation:
Waste reduction, rationalization of consumption, reuse and recycling are all ways of preserving our natural resources
Waste reduction : when we reduce the amount of wastage on items we use especially items produced from natural raw materials we will help preserve the natural resource because they can be used to produce varieties of other items
Reuse and recycling of waste products help keep our natural environment healthy thus preserving our natural resources.
