nails tools using the foot
answer:NAIL CARE TOOLS
Tools are the article used in any nail care service which are durable or permanent are hand - held are also referd to as implements.
The tools commonly used in giving manicure and padicure are the following :Callous Remover - is a tool designed to strip off calluses and corns.Cuticle Nail pusher - is a tool used to push back and loosen the cuticles.Cuticle Nipper - is an implement used to cut the cuticles.Cuticle Scissor - is an implement to cut stubborn cuticle.
hope it helps
Law of intertia
The question has an apsistance but instead of this i have an idea.
Equivalent force sould be equal to frictional force. Additionally we know that the frictional force direction is opposite direction of velocity. As a result we can easily see that if the bowling ball is on move, it will want going on. If it not, won't.
Have a good works..
To get back to its original position, it can either be in an opposite direction of the total distance travelled (much longer) or opposite direction of the displacement (shorter than the total distance travelled).
For the total distance travelled:
3 km + 4 km = 7 km
Thus, Jose needs to go back 7 km in an opposite direction (4 km West and 3 km North).
For the displacement:
Let d represent as displacement.
Let R represent as resultant.
Let Φ represents as the angle.
d1 = 3 km, 270°
d2 = 4 km, 0°
For horizontal x-axis:
For vertical y-axis:
For the resultant (or the magnitude displacement):
R = √((x)^2 + (y)^2)
For the angle (althought unnecessary):
Φ = arctan (y/x)
d1x = (3 km)(cos270) = 0 km
d1y = (3 km)(sin270) = -3 km
d2x = (4 km)(cos0) = 4 km
d2y = (4 km)(sin0) = 0 km
Summation of dx = (d1 + d2)x = 4 km
Summation of dy = (d1 + d2)y = -3 km
R = 5 km
Φ = 143.1301024°
Thus, Jose needs to go back 5 km at an angle of approximately 143.13° (or 143°).
Therefore, the magnitude of the displacement (5 km) is more convenient than using the distance travelled (7 km).
(NOTE: The illustrated angle of the vector diagram is inaccurate; but, its illustration is precise.)
