Answer:

Measuring, comparing and estimating liquid volumes are taught using metric units like liters and milliliters and customary units like quart, pints, gallons and more. Capacity is actually the amount of liquid in the container, which is also the volume of a liquid.

a golfer tees off and hits a golf ball at a speed of 31 m/s and an angle of 35 degrees. how far did the ball travel before hitti
poizon [28]
Ans: R = Ball Travelled = 92.15 meters.

Explanation:
First we need to derive that formula for the "range" in order to know how far the ball traveled before hitting the ground.

Along x-axis, equation would be:
x = x_o + v_o_xt +  \frac{at^2}{2}

Since there is no acceleration along x-direction; therefore,
x = x_o + v_o_xt

Since v_o_x = v_ocos \alpha and x_o=0; therefore above equation becomes,

x = v_ocos \alpha t --- (A)

Now we need to find "t", and the time is not given. In order to do so, we shall use the y-direction motion equation. Before hitting the ground y ≈ 0 and a = -g; therefore,

=> y = y_o + v_o_yt -  \frac{gt^2}{2}
=> t =  \frac{2v_o_y}{g}

Since v_o_y = sin \alpha; therefore above equation becomes,
t = \frac{2v_osin \alpha }{g}

Put the value of t in equation (A):

(A) => x = v_ocos \alpha \frac{2v_osin \alpha }{g}

Where x = Range = R, and 2sin \alpha cos \alpha = sin(2 \alpha ); therefore above equation becomes:

=> R = (v_o)^2 *\frac{sin(2 \alpha )}{g}

Now, as:
v_o = 31 m/s

and \alpha = 35°
and g = 9.8 m/(s^2)

Hence,
R = (31)^2 *\frac{sin(2 *35 )}{9.8}

Ans: R = 92.15 meters.

If Jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, ________ is being
Ipatiy [6.2K]

Explanation:

A force that leads to movement of an object is known as work.

The energy present in an object due to its position in a gravitational field is known as gravitational potential energy.

Kinetic energy is the energy obtained by an object due to its motion.

For example, when Jerome is swinging on a rope then there occurs movement in the swing due to which the swing has kinetic energy.

Since, a force has been applied on the swing to make it move. Hence, a work is also done.

Therefore, we can conclude that if Jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, work is being done.

Your outlets at home are rated at 120 V, i.e. the two prongs have on average a potential difference of 120V. If you transfer 2.7
hodyreva [135]

Answer:

E =230.4 MJ

Explanation:

As 1 mole of electron =  6X 10^23 particles.

charge of an electron is 1.6 X 10 ^-19 C

Finding Charge:

(6X10^23 ) (2.7)(1.6X10^-19 C)

i.e. 192 K C

now  to find the energy released from electrons

V=E/q

E=V X q

i.e E = 120 V X 192 K C

E =230.4 MJ
