Answer:
See below
Explanation:
Torgue = f * distance basically ...so if you want to increase torque with same f then the distance ( lever arm) must be increased
Answer: False
Explanation:
HR diagram or Hertzsprung-Russell Diagram shows the relation between the luminosity, spectral class, effective temperature , different stages of star in its life and absolute magnitude.
Absolute magnitude is the apparent magnitude of star when star is at a distance of 10 pc. Thus, the given statement is false. The HR diagram displays the absolute magnitude of stars not the apparent magnitude of stars.
Ions are the name for atoms that have gained or lost one or more electrons, leaving them with a net charge. For atoms that lose an electron, they gain a positive charge and become cations. For atoms that gain an electron, they take on a net negative charge and become anions.
22 ft/s^2.
explanation: In this case, the velocity has increased by 60 mph in 4 seconds, so the average increase is 60/4 = 15 mph every second, or 15 mph/s.
Usually, you will want to use the same units of time throughout. In this case, you could multiply by the number of seconds in an hour to find out the change in velocity if it carried on travelling for that length of time. This would give the acceleration in units of mph/h, or mph^2.
If you want the answer in feet/s^2, then take your 15 mph/s answer, multiply by the number of feet in a mile (to get it to feet per hour per second) then divide by the number of seconds in an hour to get it to feet per second per second, or feet/s^2.
You should get 22 ft/s^2.
Answer:
Workdone =0
Explanation:
The body is inclined at θ=30°, s=10m, m=5kg
Workdone by the object = FsCosθ
but the surface is a friction-less surface, this means coefficient of friction =0
F=μR
F=0*R
F=0
W=FScosθ
W=0*SCosθ
W=0
