True or false? Nitrogen in the atmosphere is responsible for clouds and precipitation? If not what is?

A.)

False

There reason why it's false is because Nitrogen is not responsible for clouds and precipitation. The real answer is that Water (Ocean / Other) is responsible for clouds and precipitation.

A box measuers 8 cm by 9cm by 12cm. what is its volume?

If A box measuers 8 centimeters by 9 centimeters by 12 centimeters, then its volume would be 864 centimeter³.

What is density?It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per centimeter³or kilogram per meter³.

As given in the problem we have to calculate the volume of the box having dimensions 8 centimeters by 9 centimeters by 12 centimeters,

the volume of the box= length ×width ×depth

the volume of the box = 8 centimeters ×9 centimeters × 12 centimeters,

=864 centimeter³

Thus, the volume of the box would be 864 centimeter³

To learn more about density from here, refer to the link;

To find the volume you must multiple all the sides together

8 cm * 9 cm * 12 cm = 864 cm³

8 cm * 9 cm * 12 cm = 864 cm³

An electric travel blanket uses a car's 12V supply. The current is 3A. a) What is the power of the blanket?

b) How much energy does it transfer if it is switched on for 10 minutes?

For electrical devices . . .

Power dissipated = (voltage) x (current) =

(12 V) x (3.0 A) = 36 watts .

1 watt means 1 joule per second

(36 joule/sec) x (60 sec/min) x (10 min) = 21,600 joules

If a block is in equilibrium the magnitude of the block's acceleration is

If a block is in equilibrium the magnitude of the block's acceleration is 0m/s²

According to Newton's second law, the force acting on a body is equal to the product of its mass and acceleration.

Mathematically F = ma where:

m is the mass of the object

a is the acceleration of the object

If a block is in equilibrium, the magnitude of the force acting on the block will be 0, that is F = 0

Substituting F = 0 into the formula above to calculate the acceleration;

F = ma

0 = ma

Swap sides

ma = 0

a =0/m

a = 0m/s²

This shows that if a block is in equilibrium the magnitude of the block's acceleration is 0m/s²

Answer:

zero.

Explanation:

The condition for an object to be in equilibrium is that there is no resulting force acting on it, in other words, that the force on the object is zero:

and by Newton's second law we know that

where is the mass of the object, and its acceleration.

So combining the two things:

⇒, This equation is fulfilled when

Wich tells us that for the the block to be in equilibrium, the acceleration must be zero:

A student launches a small 0.5 kg rocket with an initial speed of 30 m/s at an angle of 60°. Approximately how much time will the rocket spend in the air? Air resistance is negligible.

Answer:

Explanation:

The high reached by a proyectile in an uniformly accelerated motion is given by:

The time that the rocket spends in the air is obtained for y = 0, since this is the time that the rocket travels before touching the ground. Recall that . Solving for t:

What is something he contributed to the field of mathematics

By discovering calculus, Sir Issac Newton contributed to the field of mathematics.

Explanation:

In the early history, infinitesimal calculus, are a mathematical discipline that focuses on boundaries, derivatives, functions, infinite sequences and integrals. The work of Newton analysis began with finding the slope of any points in curve, the slope of which is constantly changing. By this way, named ‘method of fluxions’ the derivative to find the slope instead of differentiation.

This is due to the fact that he calls the "fluxion" and "fluent" variable of x and y at the instantaneous rate of curve change. He then concluded that the opposite of differentiation is integration, which he called the "method of fluents". This enabled him to develop the first fundamental calculus theorem, which states that if the function is integral and then differentiable, the basic function can be retained because differentiation and integration are inverse functions.

Newton did not publish anything about the analysis until 1693, but the mathematician Leibniz from Germany published his theory version in 1684. In addition to working on universal gravity, Newton developed three laws of motion that constitute the basic principles of modern physics. His discovery led to the development of stronger solutions to mathematical problems.
