Answer:
24.9 m
Explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as the equilateral triangle, isosceles triangle, scalene triangle, right angled triangle.
You walk 21.5 m straight east and then 12.5 m straight north. This forms a right angled triangle with a horizontal distance of 21.5 m, a vertical distance of 12.5 m and the hypotenuse is the distance between the ending and starting point. Let x represent the distance between the ending and starting point. Therefore using Pythagoras theorem:
x² = 21.5² + 12.5²
x² = 462.25 + 156.25
x² = 618.5
Taking square root of both sides:
√x² = √618.5
x = √618.5
x = 24.9 m = distance between the ending and starting point.
Explanation:
Fnet = Ft - Ff = 60N - 20N = 40N
a = Fnet / m = 40N / 25kg = 1.6m/s².
Answer:
Here
Explanation:
They don't have free electrons moving around (delocalised electrons) so they can't conduct heat and electricity which gives them a property of good insulators. The insulators stop us having an electric shock because they don't conduct electricity as we use them to insulate metal wires and other metallic things. can i have brainliest now pls!
Answer:
joules = newtons x meters
Explanation:
Work is equal to the force that is exerted, multiplied by the distance over which it is exerted.
In equation form:
joules (work) = newtons (force) x meters (distance) ,
A joule is the unit of work.
Hope this helped!! :)
