Answer:
The acceleration is in 2 D as in between east and south.
Explanation:
mass, m = 50 kg
acceleration, a = 0.25 m/s^2 horizontal
acceleration of elevator, a' = 1 m/s^2 downwards
When a person on the ground the resultant acceleration of the person with respect to the ground is between east and south direction so the path os parabolic in nature. It graph is shown below:
Answer:
Push the washing machine harder onto the surface it sits upon, increasing friction between the two.
Explanation:
Based on the sped of the waves and the tension as well as the needed wave speed, the required tension is 13.5 N.
<h3>What is the required tension?</h3>
Given the initial tension and speed, the tension that is required can be found by the formula:
= Initial tension x (Required speed / Initial speed)²
Solving gives:
= 6 x (30 / 20)²
= 6 x 9/4
= 13.5 N
In conclusion, the tension required is 13.5N.

Answer:
The identifying characteristics are zero electrical resistivity below a critical temperature, zero internal magnetic field and a critical magnetic field above which superconductivity ceases.
Explanation:
Superconductor material classes include chemical elements (example: mercury or lead)
Answer:
The car can travel V=19.8m/s without spinning out
Explanation:
Given that
Mass of the car m=1000kg
Radius of curve r =40m
frictional force R=7000N
Coefficient of friction u=?
We know that F=uR
But F=ma
F=1000*9.81
F=9810N
Therefore u=F/R
u=9810/7000
u=1.40
For the car to travel without spinning out we
Equate it centripetal force formula to frictional force formula
F=mv²/r
F=ur
hence mv²/r=uR
Making velocity subject of formula we have v²=u*r*R/m
V²=(1.4*40*7000)/1000
V²=392
V=√ 392
V=19.8m/s
