Answer:
Physical education provides cognitive content and instruction designed to develop motor skills, knowledge, and behaviors for physical activity and physical fitness. Supporting schools to establish physical education daily can provide students with the ability and confidence to be physically active for a lifetime.
The answer is crystalline solid. Crystalline solids have a regular arrangement of particles, because of that, they possess definite geometry.
This means that if you take a look at the crystal under the microscope you would notice that there is a pattern that constantly repeats. This pattern is called a unit cell, and crystal is made up of stacked unit cells.
Answer:
The resulting magnetic field is 5.021 x 10⁻⁵ T
Explanation:
Given;
current in the lightening bolt, I = 11800 A
distance from the bolt, r = 47 m
permeability of free space, μ₀ = 1.25664 × 10⁻⁶ T· m/A
Assume lightening bolt as long straight conductor, then the resulting magnetic field will be calculated as follows;
where;
B is the resulting magnetic field
I is the current in the bolt
r is the distance from the bolt
Substitute the given values and calculate B
Thus, the resulting magnetic field is 5.021 x 10⁻⁵ T
Answer:
The average speed on the second leg of the trip is 2 m/s
Explanation:
Notice that the second leg of the trip is from 8 m in the horizontal axis heading to the left to position 4 m. So the velocity is going to be negative and given by the quotient of the change in position (-4 m) divided by the time it took: 2 seconds.
This gives: -4/ 2 m/s = -2 m/s
But the speed is going to be the absolute value of the velocity, that is:
2 m/s
Answer:
Explanation:
The detailed steps and appropriate differentiation and integration is as shown in the attachment.
Starting from the equation for the profile is u/U = 3/2(y/δ) – 1/2(y/δ)3
