Answer:
2.5m/s^2
Explanation:
to answer this question the best method would be to use SUVAT equations (attached)
here we have:
U= 0ms
v=25ms
t=10sec
a=?
the best equation to use in this instance is
v = u + at
substitute in the known values:
25=a10
25/10=a
2.5m/s^2 =a
Answer: A = 0.02 m²
Explanation: Solution:
Pressure is expressed in the formula:
P = F / A where F = mg
= mg /A
= 50 kg ( 9.8 m/s²) / 25000 Pa
= 0.02 m²
I attached a Diagram for this problem.
We star considering the system is in equlibrium, so
Fm makes with vertical
Fm makes 70 with vertical
Applying summatory in X we have,
We know that W is equal to
Substituting,
<em>For the second part we know that the reaction force Fj on deltoid Muscle is equal to Fm, We can assume also that</em>
Answer:
Orbital
Explanation:
The orbitals is the area or region outside the nucleus where an electron can most likely be found
Answer: a) speed = 3.45 × 10^-2 m/s
b) speed = 1.38 × 10^-1 m/s
