Answer:
Compared to the first student, the second student did twice as much work as the first student.
Explanation:
The work done by the first student will be equal to the Force exerted by the backpack on the student carrying it multiplied by one mile (Distance). The work done by the second student will be equal to the Force exerted by the backpack on the student carrying it multiplied by two miles (Distance).
Answer:
83000 m/s
Explanation:
Using
F = Bqv....................... Equation 1
Where F = Force experienced by the charge, B = magnetic field q = charge of the particle, v = speed of the particle.
make v the subject of the equation
v = F/Bq.................... Equation 2
Given: q = 5.2×10⁻¹⁹ Coulombs, F = 9.5×10⁻¹⁵ Newtons, B = 2.2×10⁻¹ Tesla
Substitute into equation 2
v = 9.5×10⁻¹⁵ /(5.2×10⁻¹⁹×2.2×10⁻¹)
v = 8.3×10⁴ m/s
v = 83000 m/s
When the system reaches 60° North latitude after moving away from the equator and passing directly over water, it will be at a point where most of its energy is lost.
The low pressure system will dissipate its energy as it propagates through the air and more energy will be lost due to the high content of water vapor in the air above the water.
Kinetic depth cues are depth cues created by movements of the body or of objects in the environment
<span>A person’s vestibular sense helps control balance. In most mammals, the vestibular system is the sensory system that has the leading contribution to the sense of balance and spatial orientation for the purpose of coordinating movement with balance. The vestibular sense reacts to a change in the positioning of the head or when the feet are lifted of the ground. This can also help in regulating a child to keep him/her focused and attentive. Examples of activities that need vestibular input are: somersaults, swinging, hanging upside down form a monkey bar. </span>
