A block is sent up a frictionless ramp along which an x axis extends upward. The figure below gives the kinetic energy of the bl

ock as a function of position x; the scale of the figure's vertical axis is set by Ks = 46.0 J. If the block's initial speed is 4.50 m/s, what is the normal force on the block?

Kinetic energy =1/2 mv^2 

<span>m=2ke/v^2 </span>

<span>m=2(34)/3.6^2 </span>

<span>m=5.24 </span>

<span>force normal = mg </span>
<span>=5.24 x 9.8 </span>
<span>force normal = 51.4N

Is the following chemical equation balanced?<br><br> MgI2 + Br2 MgBr2 + I2 <br><br> yes<br><br> no
Brums [2.3K]

Yes

Explanation:

This chemical equation:

Mg I_2 + Br_2 \rightarrow Mg Br_2 + I_2

is balanced, because the number of atoms of each element is the same on the reactant side and on the product side. In fact:

- Mg: one atom on the left, one on the right

- I: 2 atoms on the left, and 2 on the right

- Br: 2 atoms on the left, and 2 on the right

So, the reaction is balanced.

Your pet must have current vaccinations that are required by the place (state, country, etc.) that it will be entering. Your pet would also need a health certificate that was done by a licensed veterinarian.

A man is throwing a spear from the top of a cliff, 5 metres from ground, at a 20° angle towards a fish that is 35 metres away. a
svlad2 [7]

Answer:

Horizontal component of the initial velocity=v ×cos20°

horizontal displacement= 35m

time taken. (t)=35÷(v×cos20°)

vertical component of the initial velocity= v×sin20°

vertical displacement= -5m(since it is opposite to the direction of the initial velocity. )

application of s=ut+1/2at×t. vertically,

-5=vsin20°×t -1/2 gt×t

-5= vsin20×35/vcos20-1/2×10×35×35/(vcos20×vcos20)

simplify further to obtain v and hence find the time taken

Trace fossils are recognized as evidence of which pre-existing life? plants plants and animals neither plants nor animals animal
photoshop1234 [79]

Answer:

a fossil of a footprint, trail, burrow, or other trace of an animal rather than of the animal itself.

Explanation:

Trace fossils are the indirect evidence of life in the past, such as the footprints, tracks, burrows, borings, and feces left behind by animals, rather than the preserved remains of the actual animal body itself.

Fossil is the naturally preserved remains of plants and animals which somehow get trapped in amber, hair, petrified wood, oil, coal, and DNA remnants.

When the two pistons have different surface areas, how will the pressure exerted on them compare?
andreev551 [17]

Pascal's principle says that the pressure is the same
everywhere in a confined fluid, no matter how much
or how little area you're looking at.

THAT's why hydraulic systems work ... because the
SAME pressure over MORE area adds up to MORE force.
