Answer:
2.4 m/s". 1
Explanation:
A jet with mass m = 8 x 10* kg jet accelerates down the runway for takeoff at 2.4 m/s". 1
Answer:
D
Explanation:
calculate effective resistance of the resistors
= 80 + 120
= 200
overall resistance = 48 ohms
so overall current flowing through circuit
I = V / R
I = 12 / 200
I = 0.06 A
since circuit is in series, current is same at every point so...
potential difference across 80 = R x I
= 80 x 0.06
answer is potential difference = 4.8 V

I just learned this chapter recently
-- The net vertical force on the object is zero.
Otherwise it would be accelerating up or down.
-- The net horizontal force on the object is zero.
Otherwise it would be accelerating horizontally,
that is, its 'velocity' would not be constant. That
would contradict information given in the question.
The total net force on the object is the resultant of the
net vertical component and net horizontal component.
Total net force = √(0² + 0²)
= √(0 + 0)
= √0
= Zero.
The correct answer is the last choice on the list.
Also, you know what ! ? It doesn't even matter whether the surface it's
sliding on is frictionless or not.
If the object's velocity is constant, then the NET force on it must be zero.
If it's sliding on sandpaper, then something must be pushing it with constant
force, to balance the friction force, and make the net force zero. If the total
net force isn't zero, then the object would have to be accelerating ... either
its speed, or its direction, or both, would have to be changing.
Answer:
Arctic Air masses
Explanation:
The Arctic Air masses are the world's most cold air masses. Specifically they are called Continental Arctic. Extremely cold and with very little moisture(extremely dry). These originate from north arctic region of 24 hour darkness that make the wind extremely cold and dry. The temperature in these regions are well below -50°C.
