A 3.50 kg block is pushed along a horizontal floor by a force of magnitude 15.0 N at an angle θ = 30.0° with the horizontal. The

Crank

Answer :

The frictional force on the block from the floor and the block's acceleration are 10.45 N and 0.73 m/s².

Explanation :

Given that,

Mass of block = 3.50

Angle = 30°

Force = 15.0 N

Coefficient of kinetic friction = 0.250

We need to calculate the frictional force

Using formula of frictional force

$F_{k}=\mu N$

$F_{k}=\mu (F\sin\theta+mg)$

$F_{k}=0.250\times(15\times\sin30^{\circ}+3.50\times9.8)$

$F_{k}=0.250\times41.8$

$F_{k}=10.45\ N$

(II). We need to calculate the block's acceleration

Using newton's second law of motion

$F=ma$

$a=\dfrac{F}{m}$

$a=\dfrac{F\cos\theta-F_{k}}{m}$

$a=\dfrac{15.0\cos30^{\circ}-10.45}{3.50}$

$a=0.73\ m/s^2$

Hence, The frictional force on the block from the floor and the block's acceleration are 10.45 N and 0.73 m/s².

What affects the braking distance and thinking distance

Radda [10]

Your speed is one of the only factors that has an effect on both your thinking distance and braking distance. Put simply, the faster you are going, the greater the distance travelled before you apply the brakes (thinking distance) and the vehicle comes to a complete stop (braking distance).

A gas sample occupies 4.2 L at a pressure of 101 kPa. What volume will it occupy if the pressure is increased to 235 kPa?

Dmitrij [34]

For this we want to use Boyle's Law. Boyle’s law states that the pressure and volume of a fixed quantity of a gas are inversely proportional under constant temperature conditions. The formula for this is P1V1 = P2V2. We want to solve this out so it equals V2 (Volume 2). So P1V1 / P2 = V2. Then plug in your values for the variables. So (101)(4.2) / 235 = V2; so 424.2 / 235 = V2. The final volume equals 1.81. I hope this helps, If not I am very sorry.

"In regards to the global energy budget, Earth absorbs ____________ wave radiation and emits ___________ wave radiation"

OLga [1]

Answer:

In regards to the global energy budget, Earth absorbs short-wave radiation and emits long-wave radiation.

Explanation:

It is required to tell what kind of wave radiation the earth absorbs and emits in regards to the global energy budget.

Let us discuss the global energy budget first.

The balance between the solar energy that enters Earth and the energy that leaves Earth and travels back into space is known as the global energy budget or the earth's energy budget. The visible region of the electromagnetic spectrum is where the majority of the sun's energy is found.

Therefore earth absorbs short-wave radiation and emits long-wave radiation in regard to the global energy budget.

To know more about, the global energy budget, refer to:
