22N to the right and 13N to the left
Forces are in opposite directions so you subtract the bigger force from the smaller force
Magnitude of force= 22N -13N
= 9N
net force direction is to the right
The correct answer for the question that is being presented above is this one: "an air mass that formed over land. it is cold and dry." When describing a maritime polar air mass, you might say it formed over land and is cold and dry. It's temperature c<span>an range from around freezing to near 20 degrees Celsius</span>
Answer:
i=1250000000Nm
ii=50000m/s
Explanation:
energy=force ×distance
500000N×(2.5×1000)m
=1250000000Nm
ii. Force=mass ×acceleration
500000N =40000kg ×a
500000 ÷40000=12.5a
s=1/2at^2
2500m=1/2×12.5×t^2
2500m=6.25×t^s
2500÷6.25=400
t^2=400
√t^2=√400
t=20seconds
speed=distance ×time taken
=2500m × 20s
=50000m/s
Answer:
v₁ = 5 m/s
Explanation:
We can use the law of conservation of momentum here:
where,
m₁ = m₂ = m = mass of each disk
u₁ = initial speed of yellow disk = 0 m/s
u₂ = initial speed of orange disk = 5 m/s
v₁ = final speed of yellow disk = ?
v₂ = final speed of orange disk = 0 m/s
Therefore,
<u>v₁ = 5 m/s</u>
