Answer:
its speed is insignificant before the diver's speed change, so the result does not change
Explanation:
In this exercise of conservation of the momentum, the system is formed by the diver and the Earth
initial instant (before jumping)
p₀ = 0
final instant (after jumping)
= m v + M v²
how momentum is conserved
p₀ = p_{f}
0 = m v + M v²
v² = m / M v
since the mass of the Earth is M = 10²⁴ kg
its speed is insignificant before the diver's speed change, so the result does not change
Answer:
The frictional force is 
Explanation:
From the question we are told that
The coefficient of kinetic force is μk = 0.35
The normal force felt by the puck is 
Generally the frictional force that acts on the puck is mathematically represented as
=> 
=>
Answer:
find possible answers to problems
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
Science is applied to many fields in the world such as medicine, information technology, cybersecurity, engineering, environmental etc.
Basically, knowing how to apply science simply means a scientist understands the appropriate method or technique to be used in the application of a technology such as when solving a problem.
Creativity implies being able to use an idea to proffer solutions to a problem in an intelligent manner.
Hence, a scientist should be creative in order to find possible answers to problems.
Note that the centripetal force is proportional to the square of the velocity, implying that a doubling of speed will require four times the centripetal force to keep the motion in a circle.
Answer:
Explanation:
Electric field strength, E = 5900 V/m
Magnetic field strength, B = 8.3 x 10^-3 T
The magnetic force on the charge particle is balanced by the magnetic force on the charge particle which is moving with velocity v.
qE = q v B
v = E / B
v = 7.1 x 10^5 m/s
