Answer:
26m/s²
Explanation:
Given parameters:
Mass of the student = 60kg
Weight = 1560N
Unknown:
Acceleration due to gravity = ?
Solution:
Weight is a force on a body due to gravity;
Weight = mass x gravity
Insert the given parameters and solve;
1560 = 60 x gravity
Gravity = = 26m/s²
Answer:
The maximum speed of the heart wall during the motion is 0.032 m/s
Explanation:
Given:
A = amplitude of vibration = 1.7 mm = 1.7x10⁻³m
f = frequency = 3 Hz
The angular velocity is:
The maximum speed of the heart wall during the motion is equal to:
The wavelength of light (ʎ) and the frequency (f) has the
following relationship:
ʎ = c / f
where c is the speed of light, therefore:
ʎ = (3 x 10^8 m/s ) / 6.44 × 10^13 s-1
<span>ʎ = 4.66 x 10^-6 m = 4.66 x 10^3 nm</span>
Answer:
The gravitation field strength of earth can be written as 9.8 N/Kg or 10 N/Kg. This means that an object with a mass of 1kg will be attracted towards the centre of Earth by a force of 9.8 N/kg or 10 N/kg
