Answer:

1000 m/s

Explanation:

Given that

Mass of the ball, m = 10 g = 0.01 kg

Charge of the ball, q = 2 C

Field strength of the field, E = 5 N/C

Acceleration of the ball, a = ? m/s²

We know the the equation holds,

F = qE, on substituting, we have

F = 2 C * 5 N/C

F = 10 N

Also, we know that

F = ma, and as such,

a = F / m, on substituting we have

a = 10 N / 0.01 kg

a = 1000 m/s²

Therefore, the acceleration of the ball is 1000 m/s²

How do amps correlate to brightness?

Nezavi [6.7K]

The watts determine the brightness. Watt is the unit of Power. And Power is equal to Voltage x Amps (current). So both the current and voltage determine the brightness.

A 0.600 m long pendulum is used to determine the acceleration due to gravity on a distant planet. If 20 complete oscillation are

givi [52]

Answer :

Explanation :

It is given that,

length of pendulum, l = 0.6 m

Number of oscillation, n = 20

time, t = 35.5 seconds

so, Time period, $T=\dfrac{t}{n}$

$T=\dfrac{35.5s}{20}$

we know that the time period of pendulum is given by

$T=2\pi\sqrt{\dfrac{l}{g}}$

$g=\dfrac{4\pi^2l}{T^2}$

$g=\dfrac{4\times(3.14)^2\times 0.6 \times (20)^2}{(35.5s)^2}$

$g=7.51\ m/s^2$

$g=7.52\ m/s^2$

The coefficient of kinetic friction between a suitcase and the floor is 2.76. if the suitcase has a mass of 71.5 kg, how far can

mihalych1998 [28]

suitcase can be pushed to a distance of 0.35 m

Explanation:

Work done= Ff d

w= 670 J

Ff= force of friction

d= distance

force of friction is given by Ff=μ mg

μ= coefficient of friction=2.76

m=mass=71.5 kg

so Ff= (2.76) (71.5) (9.8)

Ff=1934 N

so W= Ff d

670= 1934 d

d=0.35 m

Which of the following natural disasters are meteorologists able to predict?

Gelneren [198K]

Answer:

Hey, how you doing.

I think (warning I said think not to know!) that it is A because of the following:

Eruptions can be predicted if you have a good history of their activity. you also need to have lots of equipment constantly monitoring. Tsunamis can't really be predicted because earthquakes can't (that's why B is wrong). But however, if there is a giant asteroid impact you can predict that it will cuase i giant tsunamis.

A is the only one with 1 correct answer so I would go with it.
