Okay so yeah u have to minus then subtract then decide it it’s a method i was taught to do
Answer:
decreases.
Explanation:
When the aircraft is flies from the warm air into the colder air then its speed will be decreases.
as we know that
we know mach number is constant
so that here Mach number M is expressed as
M =
.............................1
here u is Local flow velocity with respect to the boundarie and v is the speed of sound in the medium
If the aircraft flies from hot air to cold air, the speed of sound in the medium will decrease. But the Mach number remains constant. Therefore, the local flow velocity relative to the boundaries also decreases.
1) they are attracting because if you look at the arrows they’re all pointing the same way.
2) if the magnet was turned around they would do the opposite and not attract ( this is called repulsion)
3) magnetic pole
4)magnet
5) magnetic force
6) magnetism
Hope this helps
Answer:
Explanation:
Using Hooke's law,
F = -kx
Where,
F = force of the mass
k = spring constant/stiffness
x = length of the spring
Given:
F1 = m1*a
= 4.1 * 9.81
= 40.221 N
F2 = m2*a
= 1.5 * 9.81
= 14.715 N
x1 = 2.9 cm
F1/x1 = F2/x2
Therefore,
x2 = (14.715 * 2.9)/40.221
= 1.06 cm.
