Answer:

E. 3h

Explanation:

We know that

u = 0 m/s.

velocity after t = 1s

v = u+gt = 0+9.81 x 1s= 9.81 m/s

distance covered in 1st sec

= =>> ut+0.5 x g x t²

=>>0 + 0.5x 9.81 x 1 = 4.90m

Let 4.90 be h

distance travelled in 2nd second will now be used

So velocity after t = 1s

=>>1 x t+ 0.5 x g x t²

=>9.81x 1 + 0.5 x 9.81 x 1 = 3 x 4.90

So since h= 4.90

Then the ans is 3x h = 3h

In an arcade game a 0.117 kg disk is shot across a frictionless horizontal surface by compressing it against a spring and releas
Illusion [34]

Find the speed with which the disk slides across the surface

Answer:

\boxed{2.85 m/s}

Explanation:

The Potential energy of spring is transformed to kinetic energy hence

0.5kx^{2}=0.5mv^{2}\\kx^{2}=mv^{2}\\v=\sqrt{\frac {kx^{2}}{m}}

Here k is the spring constant, x is the extension of spring, v is the velocity of disk and m is the mass of the disk.

Substituting 0.117 Kg for m, 194 N/m for k and 0.07 m for x then

v=\sqrt{\frac {194\times 0.07^{2}}{0.117}}=2.850401081 m/s\approx \boxed{2.85 m/s}

Honey bees can acquire a small net charge on the order of 1 pC as they fly through the air and interact with plants. Estimate th
murzikaleks [220]

Answer:

3.35\cdot 10^{-16}N

Explanation:

The force exerted on a charged particle due to a magnetic field is given by:

F=qvB sin \theta

where

q is the charge of the particle

v is the velocity of the particle

B is the magnetic field strength

\theta is the angle between the directions of B and v

In this problem we have:

q=1 pC=1\cdot 10^{-12} C is the charge of one honey bee

v=15 mi/h = 6.7 m/s is the velocity of the bee

B=5.0\cdot 10^{-5} T is the average strength of the Earth's magnetic field

\theta=90^{\circ}, because the bee flies east to west while the Earth's magnetic field is south to north

Substituting into the equation, we find:

F=(1\cdot 10^{-12}C)(6.7 m/s)(5.0\cdot 10^{-5} T)(sin 90^{\circ})=3.35\cdot 10^{-16}N
