Answer: F = 5kg x 1 m/s2 = 5 N

Explanation:

Hi, to answer this question we have to apply the next formula:

Force (F) = mass x acceleration

Replacing with the values given and solving for F (force)

F = 5kg x 1 m/s2 = 5 kgm/s2

Since 1 Newton (N) = 1 kgm/s2

F = 5N

An electron is accelerated through 2.40×10³V from rest and then enters a uniform 1.70-T magnetic field. What are(b) the minimum

Korolek [52]

The maximum value of Force is 7.88x $10^{-12}$

The minimum value of magnetic force is 0

Potential V=2.40x $10^{3}$ .

Magnetic field = B = 1.70 T.

we need to find

a) The maximum value of Force

Since the particle is moving from rest, the potential energy change is 2.40x $10^{3}$ ?

Potential Energy= vq= 2,40x $10^{3}$ x (-1.6 x 10x $10^{-19}$ %).

= -8.84x $10^{-16}$

Now this will be equal to 1/2 mv²

= 1/2 mv²= 8.84x $10^{-16}$ .

v=2.903x $10^{7}$ m/s :

Wow Fmax = qvb

=1.6x $10^{-19}$ x2.903x $10^{7}$ x1.70 .

=7.88x $10^{-12}$

b) The minimum value of magnetic force

The minimum Value of magnetic force will be

when sinθ=0

The minimum value is 0

Why is specific heat important

Ad libitum [116K]

Hey!!

here is your answer >>>

Specific heat is the amount of heat required to raise the temperature of a unit substance!. The most common example!. The specific heat of water is 1 !. And, lot of plays and animals live under the water and if the specific heat of the water would be low, then the aquatic organisms would die, but the specific heat is high and it is hard for the sun to increase the temperature!.

Hope my answer helps!

What is the average velocity of the time interval 0 to 4 seconds

Anvisha [2.4K]

Average velocity over a given time interval is the distance traveled divided by the time:
$v= \frac{60m-20m}{4s-0s} =40/4=10 \frac{m}{s}$

"A proton is placed in a uniform electric field of 2750 N/C. You may want to review (Page) . For related problem-solving tips an

tekilochka [14]

To solve this problem we will start from the definition of Force, as the product between the electric field and the proton charge. Once the force is found, it will be possible to apply Newton's second law, and find the proton acceleration, knowing its mass. Finally, through the linear motion kinematic equation we will find the speed of the proton.

PART A ) For the electrostatic force we have that is equal to

$F=qE$
