G is actually the universal gravitational constant.
6.674×10−11 m3⋅kg−1⋅s−2
This proportional to the product of the two objects masses and the inverse square of their distance.
This different from g which the local gravitational constant.
Answer:
The distance is 1.4 km.
Explanation:
Given that,
Initial velocity u= 1.7 m/s
Accelerate a= 3.0 m/s²
Time = 30 s
We need to calculate the distance
Using equation of motion
Where, u = initial velocity
a = acceleration
t = time
Put the value in the equation
Hence, The distance is 1.4 km.
In 9 sec, it increases the angular velocity by (0.45 x 9) rad/s which will give us 4.05 rad/s
Now get the angular velocity and divide it 2pi = 4.05 by 2(pi) to give how many revolutions 4.05 rad is equivalent to = 0.6446 rps
Them, multiply this by 60 to get it from rps to rpm increase (0.6446 x 60)=38.676 rpm
Add this and the starting revolution frequency of 49 rpm to give: (49 rpm + 38.676 rpm) = 87.6760 rpm
Newton's new “reflecting telescope” was more powerful than ... Before Newton, scientists primarily adhered to ancient theories on ... laws of motion laid the groundwork for classical mechanics. Newton's research on motion helped give credibility to the heliocentric view. Newton also helped pioneer telescopic innovations, and he is sometimes credited with inventing the first reflecting telescope. He also conducted experiments using the prism, and developed a theory about the nature of color and light.
Answer: Option 5.
Decreases increases increases.
Explanation:
Electromagnetic spectrum refers to differences in frequencies, wavelengths and photon energies of electromagnetic radiation.
From the top of the list to the bottom i.e from radio waves, infrared waves, visible lights, ultraviolet radiation, gamma radiation, wavelengths decreases, the frequency increases as the photon energy increases.
The electromagnetic radiations : radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays have high-frequency and short wavelengths. Their wavelengths decrease. The photon energy is directly proportional to wave frequency.
