Answer:

W = 285.62 N

Explanation:

It is given that,

Mass of Jessica is 55 kg

Slope of the hill is 32 degrees

We need to find the component of her weight that is along her direction of motion.

The component along her direction of motion is shown in attached figure. It means

W_y=mg\sin\theta\\\\W_y=55\times 9.8\times \sin(32)\\\\W_y=285.62\ N

So, the component of her weight that is along her direction of motion is 285.62 N.

nekit [7.7K]
Find the volume of the bottom and top separately and then add them.
Cylinder volume is the area of the bottom times the height
(22/7)(5^2)•175=13750 ft^3

The volume of a sphere is
V=(4/3)(22/7)r^3
where r is the radius. Here that's also 5 since it fits on the cylinder.
Also we only want half the sphere so use
V=(2/3)(22/7)•5^3=261.9 ft^3
Which we round upto 262.
Now add the parts together
13750+262=14,012 ft^3

Two objects 5 kg and 7 kg are attached to the end of inextensible string which passes over frictionless pulley
Bumek [7]

Answer:

ans:

tenson(T) = 20 N

acceleration (a) = 2.86 m/s

Explanation:

T + mg = Mg

T = Mg - mg

T = g( M - m )

T = 10× ( 7-5 )

T = 20 N

again;

T = 20

Ma = 20

a = 20 / 7

= 2.86 m/s

An electron is pushed into an electric field where it acquires a 1-v electric potential. if two electrons are pushed the same di
liq [111]

Given here that through the same region 2 electrons are pushed by same distance

As we know that electric potential can be relate with electric field by following relation

\delta V = E . d

Since the two electrons are pushed through same electric field by same distance

So the product of E and d will be same

So the electric potential will be same as initial

so V = 1 volt for two electrons

Is it true or false that on the Celsius temperature scale, there are no negative numbers? If false, why?
jeka57 [31]
The Celsius Temperature scale has negative values, anything lower than 32 Fahrenheit/0° is negative, for reference using the celsius scale water freezes at 0° and boils at 100°, hope this helps!
