Two Factors That Affect How Much Gravity Is on an Object. Gravity is the force that gives weight to objects and causes them to fall to the ground when dropped. Two major factors, mass and distance, affect the strength of gravitational force on an object.

attractive force only means force pulling two things together but factors affecting the force depend on the kind of force. gravity is an attractive force n the other helper gave the factors.

another attractive force is magnetic force and how strong the magnet will determine how strong the attractive force.

electrostatic force can also be attractive and the amount of electric charge will determine the force.

A pail of water is rotated in a vertical circle of radius r = 1.6 m . The acceleration of gravity is 9.8 m/s 2 . r v What is the

Snowcat [4.5K]

Answer:3.95 m/s

Explanation:

Given

radius of circle $r=1.6 m$

Water will not spill if the centripetal acceleration is greater than acceleration due to gravity

i.e. $a_c\geq g$

$a_c=\frac{v^2}{r}$

$\frac{v^2}{r}\geq g$

$v_{min}=\sqrt{gr}$

$v_{min}=\sqrt{9.8\times 1.6}$

$v_{min}=\sqrt{15.68}$

$v_{min}=3.95 m/s$

Steam enters a well-insulated nozzle at 200 lbf/in.2 , 500F, with a velocity of 200 ft/s and exits at 60 lbf/in.2 with a velocit

Ede4ka [16]

Answer:

$386.2^{\circ}F$

Explanation:

We are given that

$P_1=200lbf/in^2$

$P_2=60lbf/in^2$

$v_1=200ft/s$

$v_2=1700ft/s$

$T_1=500^{\circ}F$

$Q=0$

$C_p=1BTU/lb^{\circ}F$

We have to find the exit temperature.

By steady energy flow equation

$h_1+v^2_1+Q=h_2+v^2_2$

$C_pT_1+\frac{P^2_1}{25037}+Q=C_pT_2+\frac{P^2_2}{25037}$

$1BTU/lb=25037ft^2/s^2$

Substitute the values

$1\times 500+\frac{(200)^2}{25037}+0=1\times T_2+\frac{(1700)^2}{25037}$

$500+1.598=T_2+115.4$

$T_2=500+1.598-115.4$

$T_2=386.2^{\circ}F$

Which type of energy is associated with electric currents?

zalisa [80]

B. Electrical energy

Among the choices given, the type of energy associated with electric currents is electrical energy. By its definition, electric current is the flow of charged particles through a conductor or a conduction medium, for example, a wire. Basically, it involves electricity. It is similar to water current but instead of water molecules, charged particles move down a conductor. These charged particles are mostly electrons which move freely and at random. When all the free electrons move in the same direction, a current is created.
