A block weighing 10 newtons is resting on a plane inclined 30° to the horizontal. What is the magnitude of the normal force acti
aleksley [76]

Magnitude of normal force acting on the block is 7 N

Explanation:

10N = 1.02kg

Mass of the block = m = 1.02 kg

Angle of incline Θ =  30°

Normal force acting on the block = N

From the free body diagram,

N = mgCos Θ

N = (1.02)(9.81)Cos(30)

N = 8.66 N

Rounding off to nearest whole number,

N = 7 N

Magnitude of normal force acting on the block = 7 N

A futuristic design for a car is to have a large solid disk-shaped flywheel within the car storing kinetic energy. The uniform flywheel has mass 370 kg with a radius of 0.500 m and can rotate up to 320 rev/s. Assuming all of this stored kinetic energy could be transferred to the linear velocity of the 3500-kg car, find the maximum attainable speed of the car.

The boiling point of a substance is _72 degree Celsius. This temperature will be equivalent to Kelvin scale is-------.
Vlada [557]

Answer:

345 K

Explanation:

Temperature can be defined as a measure of the degree of coldness or hotness of a physical object.

Generally, it is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).

<u>Given the following data;</u>

  • Boiling point = 72°C

<em>To convert the temperature in degree Celsius to Kelvin, we would use the following mathematical expression;</em>

Kelvin = 273 + °C

Substituting into the formula, we have;

Kelvin = 273 + 72

<em>Kelvin = 345 K</em>

<em>Therefore, the temperature of 72°C will be equivalent to 345 K on the Kelvin scale.</em>

How are Earth, the Moon and Sun alligned during a neap tide?
Tpy6a [65]
Neap tides occur at or immediately after the First Quarter
and Third Quarter moon phases.  At those times, the moon
is 'to the side' of the Earth.  I mean, the sun, Earth, and Moon
make a right angle, with Earth at the vertex.
