Answer:
mass and volume
Explanation:
matter is anything that has mass and occupies space(volume)
The product of √30 and √610 is 10√183.
√30 = √(2×3×5)
and √610 = √(2×5×61
Since 61 can't be factorised further.
Therefore, the value of √30×√610 is
= √(2×3×5×2×5×61)
= 2×5×√(3×61)
=10√183
Answer:
The bulk modulus of the liquid is 1.229 x 10¹⁰ Pa
Explanation:
Given;
density of liquid, ρ = 1400 kg/m³
frequency of the wave, f = 390 Hz
wavelength, λ = 7.60 m
The speed of the sound is given by;
v = fλ
v = 390 x 7.6
v = 2964 m/s
The bulk modulus of the liquid is given by;
where;
B is bulk modulus
B = (1400)(2964)²
B = 1.229 x 10¹⁰ N/m²
B = 1.229 x 10¹⁰ Pa
Therefore, the bulk modulus of the liquid is 1.229 x 10¹⁰ Pa
According to the second law of motion, force is equal to the product of mass and acceleration. This means force is proportional to mass. Hence when mass increases, it is understood that force should increase as well. In this case,the answer to this problem is A.
Explanation:
The speed of an object can be found from the slope of the line which plots its distance over time. The object in motion's speed can be compared with another by the value of the slope or the steepness of the line. The steeper the slope is, the greater the speed.
