1 answer:
lisabon 2012 [21]3 years ago
5 0

Answer:

<h2>1116.9 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 438 × 2.55

We have the final answer as

<h3>1116.9 N</h3>

Hope this helps you

A 86.3 μC charge has a potential of 17.5 V. Determine how much kinetic energy, in eV, this charge could have.
almond37 [142]

Answer:

9.44 eV

Explanation:

q = Amount of charge = 86.3 μC = 86.3 x 10⁻⁶ C     (Since 1 μC =  10⁻⁶ C)

V = Electric potential of the charge = 17.5 Volts

U = Amount of electric potential energy carried by charge

Amount of electric potential energy carried by charge is given as

U = q V

Inserting the values

U = (86.3 x 10⁻⁶) (17.5)

U = 0.00151 J

U = \frac{0.00151}{1.6\times 10^{-19}}

U = 9.44 eV

KE = Kinetic energy the charge could have

Using conservation of energy

KE = U

KE = 9.44 eV

What is the speed over the ground of a mosquito flying 2 m/s relative to the air against a 2 m/s headwind?
salantis [7]

We have that the speed over the ground of a mosquito flying 2 m/s relative to the air against a 2 m/s headwind is

X=0m/s

From the question we are told that

mosquito flying 2 m/s

against a 2 m/s headwind

Generally

The speed over the ground is the Flight Speed minus resistance speed

Generally the equation for the  speed over the ground  is mathematically given as

X=Flight Speed-resistance speed

Therefore

X=2-2

X=0m/s
