Answer:

80m/s²

Explanation:

First, use the equation below to find the strength of a planet/moon's satellite field and acceleration rate.

This is G × Mass of planet/moon ÷ r² (which is the distance or conversely radius squared)

Then you want to plg in all your values, which are going to be the gravitational constant, Kling's mass, and Kling's radius.

Remember that Earth's mass is equal to 5.97 × 10∧24 kg and its radius is exactly 6,731 km, so this will help you figure out your values for any other problems like this .

Also that the big ( G) you see is = 6.673×10∧-11.

Now for step two, which is the last thing you need to do. Once you've simplified the above equation, take the value you found, which should ≈ 7.85, and then multiply it by the force of gravity on Earth.

Once you multiply 7.85 by 9.8 m/s², the answer will be = 76.93 or ≈ 80m/s².

16. The energy absorbed in 10minutes by an electrical heater is 1.5 MJ. The supply voltage is 240 V. calculate: a) The current d
dsp73

Answer:

If by 1.5 MJ you mean 1.5E6 Joules then

W = P t    = power X time

W / t = P   power

P = 1.5E6 J / 600 sec = 2500 J / s

P = I V

a) I = 2500 J/s / (240 J/c) = 10.4 C / sec  = 10.4 amps

b) Q = I t = 10.4 C / sec * 300 sec = 3120 Coulombs

c)  E = P * t = 2500 J / sec * 100 hr * 3600 sec / hr = 9.0E8 Joules

A scientist discovered an elementary particle paired with another particle. It has a positive charge equal to two–thirds of the
julia-pushkina [17]
W boson has +1e or - 1e charge, Z boson has 0 charge.

Leptons have +1e, -1e or 0 charge.

Photons have 0 charge.

Only quarks have a charge of +2/3e or -1/3e of an electron charge. 

To be exact, only up-type quarks (Up, Down and Top quarks) have a +2/3e or two thirds of an electron charge.

So the correct answer is D) Quark.
