Answer:
4.9N
Explanation:
The formula for weight is F = ma.
You plug in the mass of 0.5kg and an acceleration of 9.8 to get
F = (0.5)(9.8)
F = 4.9N
The correct answer for this question is this one: C) 2.5s. T<span>he period and frequency of a water wave if 4.0 complete waves pass a fixed point in 10 seconds is that 2.5 s
</span>
Here are the following choices:
<span>A) 0.25s
B) 0.40s
C) 2.5s
D) 4.0s</span>
B because I just think it’s the right answer because drawing a PV diagram for this cycle is the best answer even though it might be a stupid so I would not pay attention to my response because I’m just getting this for points but let me know if it is the right answer because right now I’m just guessing.
Answer:
Time taken to accelerate to 48 m/s = 8 seconds
Explanation:
Initially the object is moving south at = 
So, initial velocity of the object =
Acceleration caused by the force = 4 
Final velocity towards south = 
Using equation of motions:
where
final velocity
initial velocity
acceleration
time
Plugging in values.
Subtracting both sides by 16
Dividing both side by 4.
∴ 
Time taken to accelerate to 48 m/s = 8 seconds
