Answer:
Time taken by the arrow to travel along to hit the ground is 0.55 seconds.
Explanation:
The only "force" acting on the "crossbow" to cause it to "hit" the ground is "gravity". There is no initial velocity downward when it shoot.
d = the displacement of the object
t = the time for which the object moved
a = acceleration of the object
= the initial velocity of the object
Given values
d = 1.5 m
t = unknown
Square root both sides
t = 0.55 s
It should be true: electrons low from negative toward positive to negative toward positive because opposite charges attract each other.
I hope this was correct
Answer:
134.77 mm
Explanation:
Wave length of light λ = 599 x 10⁻⁹ m
Slit separation d = 20 x 10⁻⁶ m
Screen distance D = 3 m
Distance of second dark fringe from centre
= 1.5 x λ D / d
Putting the values given above
distance = 
= 134.77 x 10⁻³ m
= 134.77 mm.
Answer:
I believe it's A. An installment credit has an interest rate, repayment terms and fees, and fixed payment.
Answer:
I=1.48 A
Explanation:
Given that
B=3.1 x 10⁻5 T
b= 4.2 cm
l= 9.5 cm
The relationship for magnetic field and current given as
Where
By putting the values
D=26.03 m⁻¹
I=1.48 A
