10 newton east is the answer because the two force vector form 0 degree angle with each other
Answer:
True
Explanation:
Physical fitness is defined as the health state of the body and its ability to carry on with the daily occupation as well as sports.
The everyday lifestyle affects this physical fitness, in case you are not used used to "moving" in your daily life, your body will be sort of lazy and lack the power and ability to carry on with the daily occupation as well as sports.
In case your daily lifestyle involved motion, your body will be used to doing activities which will help improve your physical fitness.
Hope this helps :)
Answer:
Explanation:
(i) μs = F/N = mgsinθ/mgcosθ = tanθ
tanθ = 0.3
θ = 16.7°
(ii) a = F/m
a = (mgsinθ - (μk)mgcosθ) / m
a = g(sinθ - (μk)cosθ)
a = 9.8(sin16.7 - (0.2)cos16.7)
a = 0.94 m/s²
(iii) s = ½at²
t = √(2s/a)
t = √(2(1)/0.94)
t = 1.5 s
<span>The potential energy is mgh. The kinetic energy is (1/2)mv^2. Total mechanical energy means the sum of those. The velocity is 0 since its just hanging.
A 0.100-kilogram apple falls from a height of 1.50 meters to 1.00 meters. Ignoring frictional effects, what is the kinetic energy of the apple at this height? Its equal to the change in PE from 1.5 meters to 1.0 meters. PE = mgh.</span>
Answer:
David will drive a total of 7 hours and 15 minutes to see his grandma.
Explanation:
To solve this problem, it is easiest to set up a dimensional analysis problem that allows us to multiply and cancel units. This is shown below.
435 miles * 1 hour/60 miles
Since miles appears both in the numerator and denominator, we know that this unit will cancel, so our answer will be in units of hours.
435/60 = 7.25 hours
This means that David's trip will take 7.25 hours. However, the question asks for the time David will travel in hours and minutes, so we must convert this answer into those units.
We can keep the number 7 because it represents the number of full hours David will drive, but we must convert 0.25 hours into minutes. Since there are 60 minutes in 1 hour, we can multiply 0.25 * 60 to find out how many minutes David will drive.
0.25 * 60 = 15
Therefore, David will drive a total of 7 hours and 15 minutes to see his grandma.
Hope this helps!
