Find the magnitude of the net gravitational
force exerted by the two larger masses on the
70.9 kg mass. The value of the universal
gravi
tational constant is 6.672 x 10-N m2/kg?

Leaving the distance between the 122 kg
and the 278 kg masses fixed, at what distance
from the 278 kg mass (other than infinitely
remote ones) does the 70.9 kg mass experience
a net force of zero?
Answer in units of m.
Answer in units of m

Scientists use laser range-finding to measure the distance to the moon with great accuracy. a brief laser pulse is fired at the moon, then the time interval is measured until the "echo" is seen by a telescope. a laser beam spreads out as it travels because it diffracts through a circular exit as it leaves the laser. in order for the reflected light to be bright enough to detect, the laser spot on the moon must be no more than 1.0 km in diameter. staying within this diameter is accomplished by using a special large-diameter laser. part a if λ = 540nm , what is the minimum diameter of the circular opening from which the laser beam emerges? the earth-moon distance is 384,000 km. express your answer to two significant figures and include the appropriate units.

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.
