Answer:

T=26.03 N

Explanation:

Given that

Distance between poles = 12 m

Mass of block m= 4 kg

Sag distance = 5 m

Lets take tension in the clothesline is T.

The component of tension in vertical direction will be T cosθ.

By force balancing

2 T cosθ = 40

here tan\theta =\dfrac{5}{6}

θ=39.80°

2 T cos39.8 = 40

T=26.03 N

20 miles per hour north is an example of ______
timofeeve [1]
B. It's an example of velocity due to the fact that it has a measurement of speed, divided by time, and has a specific direction. Acceleration doesn't have any direction on it, but has speed divided by time. C and D have a different mode of measurement despite of the fact that it still needs meters/miles/km.

the natural radioactivity is done by(controlling the nuclear energy-no ability to control the nuclear energy-both of them)​
just olya [345]

Answer:

Nuclear power plants are fueled by uranium, which emits radioactive substances. Most of these substances are trapped in uranium fuel pellets or in sealed metal fuel rods. However, small amounts of these radioactive substances (mostly gases) become mixed with the water that is used to cool the reactor.

If the current throught a 6 Ω resistor is 7 A, what is the power absorbed by the resistor? Answer to the nearest 1 W.
Stells [14]

Answer:

294 W

Explanation:

Electrical power: This can be defined as the rate at which electrical energy is used or dissipated. The S.I unit of electrical power is Watt(W).

The expression of electrical power is given as,

P = I²R................... Equation 1

Where P = power, I = current, R = Resistance.

Given: I = 7 A, R = 6 Ω

Substitute into equation 1

P = (7)²(6)

P = 294 W.

Hence the power power absorbed by the resistor is 294 W
