Answer:
False
Explanation:
The charge on an electron as well as proton is same. The difference between electron and proton is that the electrons have a negative charge while the protons have positive charge.
The weight of an electron is, 
while the weight of a proton is 
.
Therefore, the given statement "A proton carries positive charge, and weights the same as an electron." is false.
Answer:
The speed of the wave as it travelled through the brass bell is;
B. 4,700 m/s
Explanation:
The given parameters are;
The wavelength of the sound wave produced from the brass bell, 
= 3.5 m
The wavelength of the wave in the brass bell, 
= 47 m
The frequency of the wave in the brass bell, f = 100 Hz
The given equation for wave speed, v = f × λ
Therefore, the speed of the wave as it travelled through the brass bell, 
, is given as follows;
= f × = 100 Hz × 47 m = 4,700 m/s
The speed of the wave as it travelled through the brass bell = = 4,700 m/s

Answer:
2361 Newtons
Explanation:
From the second Newton's law of motion;
F = ma
In this case;
we are given;
Mass as 9.5 g
Initial speed as 0 m/s
Final velocity as 650 m/s
Distance is 0.85 m
Using the equation;
V² = U² + 2as
But u = 0
v² = 2as
Therefore;
a = v² ÷ 2s
= 650² ÷ 2(0.85)
= 248,529.40 m/s²
But;
F = ma
= 0.0095 kg × 248,529.40 m/s²
= 2361 Newtons
Therefore;
The average net force required to accelerate the bullet is 2361 Newtons.
Answer:
25 cm³
Explanation:
In the conversion of units, we know that are one cubic centimeters (cm³) in a milliliter (mL) .
1 milliliter = 1 cubic centimeter
25 milliliters = 25 cubic centimeters
Therefore, a volume of 25 milliliters is the same as a volume of 25 cubic centimeters.
This ultimately implies that, the volume of an object in milliliters is equivalent to its volume in cubic centimeters.
