Answer:
a baseball flying through the air at 90 miles per hour
Explanation:
For the question, Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If the velocity is doubled the kinetic energy will increase by a factor of four.
Answer:

Explanation:
Given,
Red light wavelength = 633 nm
width of slit = 0.320 mm
distance,d = 2.60 m
Condition of first maximum


m = 1


Width of the first minima



Now, width of the central region



Answer:
I guess sound wave I s gonna be d right answer
Explanation:
cos sound doesnt has weight and occupies space
Answer:
The initial current in the circuit is 0.1873 mA
Explanation:
Given;
capacitance is given as 3.67 x 10⁻⁶ F
resistance is given as 8010 Ω
voltage across the circuit is 1.5 V
Since the capacitor is initially uncharged, the capacitive reactance is zero.
From ohms law;
Voltage across the circuit is directly proportional to the opposition to the flow of current.
V = IR
I = V/R
I = 1.5/8010
I = 0.0001873 A = 0.1873 mA
Therefore, the initial current in the circuit is 0.1873 mA
I think it`s D but iam not so sure
