A force vector has a magnitude of 599 newtons and points at an angle of 40.8° below the positive x axis. What is the x scalar co

ASHA 777 [7]

Answer:

$F_{x}=453.44N$

Explanation:

Given data

Force F=599 N

Angle α=40.8°

To find

x scalar component

Solution

The Scalar x component can be found by

$F_{x}=FCos\alpha \\F_{x}=599Cos(40.8)\\F_{x}=453.44N$

The Scalar y component can be found by

$F_{y}=-FSin\alpha \\F_{y}=-599Sin(40.8)\\F_{y}=-391.4N$

A 20 N unbalanced force causes an object to accelerate at 1.5 m/s2. What is the mass of the object?

kicyunya [14]

As per Newton's II law we know that

$F = ma$

here we know that

$F = 20 N$

$a = 1.5 m/s^2$

now the mass of the object will be given as

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

$m = \frac{20}{1.5}$

$m = 13.3 kg$

so mass of the object will be 13.3 kg

An ice rink is 200 feet long and 85 feet wide. The four corners of the rink are rounded to a radius of 24 feet. What is the surf

Nastasia [14]

Answer:

16,506 ft²

Explanation:

There are different ways you can divide the area using rectangles and circles. One way is to find the area of the entire width and length, then subtract the empty areas in the corners.

If we take the empty areas and put them together, we find their area is the area of a square minus the area of a circle.

A = (2r)² − πr²

A = 4r² − πr²

A = (4 − π) r²

So the area of the rink is:

A = WL − (4 − π) r²

A = (85)(200) − (4 − π) (24)²

A ≈ 16,506 ft²

What uniform magnetic field, applied perpendicular to a beam

schepotkina [342]

Answer:

The magnetic field is $2.11\times10^{-5}\ T$

Explanation:

Given that,

Speed $v=1.30\times10^{6}\ m/s$

Radius = 0.350 m

We need to calculate the magnetic field

Using formula of magnetic field

$B =\dfrac{mv}{qr}$

Where, m = mass of electron

v = speed of electron

q = charge of electron

r = radius

Put the value into the formula

$B=\dfrac{9.1\times10^{-31}\times1.30\times10^{6}}{1.6\times10^{-19}\times0.350}$

$B=2.11\times10^{-5}\ T$

Hence, The magnetic field is $2.11\times10^{-5}\ T$

Which statement best describes the difference between ultraviolet light and infrared light

lys-0071 [83]

The infrared (IR) and the ultraviolet(UV) represent the two extremities of the visible spectrum (400-700nm). While IR represents electromagnetic radiation
with wavelengths longer than those of visible light, UV represents wavelengths
shorter than visible light.
