if the pendulum was dropped so that the linear velocity when passing through the bottom of the swing were doubled for the same radius then the centripetal force would be
quadrupled
if the pendulum were dropped so that the linear velocity when passing through the bottom of the swing was the same for a radius twice as great then the centripetal force would be
halved
if the pendulum were dropped so that the centripetal force was the same when passing through the bottom of the swing but the linear velocity was twice as great, then the radius of orbit would be
quadrupled
The weight of the 100 gram mass is 0.98 newtons. say the pendulum is dropped from an angle such that the centripetal force is measured to be 2 newtons. if the force sensor were zeroed before attaching the 100 gram mass then what would the force sensor rea
2.98 Newtons
torque is defined as
the product of the distance a force acts from some pivot point and the component of the force which is perpendicular to the distance vector
to double the period of a simple pendulum the length of the pendulum must be
quadrupled
if the tension in the string is increased keeping the linear mass density of the string fixed, the speed of the wave will
increase
if you quadruple the hanging mass in order to increase the tension, the wavelength would be
doubled
if the speed of sound stays the same while its frequency is doubled the the wavelength is
halved
you change the oscillator frequency and set up a standing wave with a different number of nodes. you measure the resulting wavelength without changing the hanging mass. when you multiply this wavelength by the frequency to obtain the corresponding wave sp
about the same as before
to raise the temperature of a stationary piece of copper from 30 to 40 it takes
the same amount of heat as it takes to raise the temperature from 20 to 30
the specific heat of copper is about 3 times the specific heat of lead. the amount of heat needed to raise the temperature of one gram of stationary copper sample by one degree Celsius is
three times the amount of heat needed to raise the temperature of a gram of lead by one degree
the pressure of a gas is 100 kPa when the temp is 270 K. what is the pressure when the temperature is 540 K is the volume of the gas is constant.
