The magnitude of the charge is 12 N in the opposite direction of the field.
What is Electric field?The term electric field refers to the region in space where the effect of a charge is felt. In this case, we are told that the magnitude of the charge is –0.06 C.
Hence;
E = F/q
F = Eq
F = –0.06 C * 200 N/C
F = 12 N
Hence, the magnitude of the charge is 12 N in the opposite direction of the field.

What must be the acceleration of a box that is pushed with 86 N of force and experiences 29 N of friction? The mass of the box is 5 kg.
Answer:
In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction). The orientation of an object's acceleration is given by the orientation of the net force acting on that object. The magnitude of an object's acceleration, as described by Newton's Second Law, is the combined effect of two causes: the net balance of all external forces acting onto that object — magnitude is directly proportional to this net resulting force; that object's mass, depending on the materials out of which it is made — magnitude is inversely proportional to the object's mass.
Explanation:
A footballer kicks a football of mass 430 g and it flies off at a speed of 8 m/s. What is the KE of the football?
Answer:
13.76 Joules
Explanation:
The SI units for joules are defined to be kilogram*meters per second. Therefore, we must turn the grams to kilograms by dividing the answer by 1,000. This is due to 1,000 grams being in a single kilogram. Kinetic energy is defined to be:
[tex]KE=\frac{1}{2} mv^2[/tex]
Therefore:
[tex]KE=\frac{1}{2} (0.43kg)(8m/s)^2=13.76J[/tex]

What would be the final velocity, in m/s, if a disk of the same mass and radius as the hoop rolled down the hill?.
The final velocity will be [tex]\rm V= \sqrt{\frac{4gh}{3} }\ m/sec[/tex]. Speed is a scalar quantity. It is a time-based component. Its unit is m/sec.
What is velocity?The change of distance with respect to time is defined as speed.
From the law of conservation of energy:
[tex]\rm KE_i + PE_i = KE_f+PE_f \\\\ 0+mgh = \frac{1}{2} mV^2 +\frac{1}{2} I\omega^2[/tex]
The moment of inertia of the disc;
[tex]\rm I= mr^2[/tex]
It can also be found as;
[tex]\rm I = \frac{V}{r} \\\\[/tex]
Put the obtained values;
[tex]mgh = \frac{1}{2} mv^2+\frac{1}{2} mv^2=mv^2\\\\ mgh = mv^2 \\\\ v=\sqrt{gh}[/tex]
if a disk of the same mass and radius as the hoop rolled down the hill;

If the height gain of each step was 0.20 m , and the mass of the runner was 69 kg , what was his average power output during the climb
Answer: 370 W
Explanation:
Find the total height
1576 steps * 0.2 metres = 315 m
Energy = mgh = 69 * 9.8 * 315
=2.12 * 10^5 J
Power = energy / time
Time = 9*60 +33 = 573 sec
So power = energy/time = 370 W

Acceleration
Explanation:
The particle is moving in a straight line. That means there’s no change in the path of the particle in the entire trip. It is moving with constant acceleration, meaning the particle doesn’t change its acceleration at all. The acceleration direction is in the same direction of instantaneous velocity
A weightlifter holds a barbell motionless at her chest as she prepares to lift it over her head. The work done by the weightlifter to hold the barbell in this position is
Answer:
it's a bit of a trick question
Explanation:
W = distance X force
when the distance is zero, the work is zero. So when she holds the weight without moving them she is doing no work. But, to be fair, that's just the wording, what "work" means. she is actually producing a force, that is equal to the weight of the barbells, to hold them against the graviational force.

A person is attracted towards the center of Earth by a 440 N gravitational force. The force with which Earth is attracted toward the person is 440 N.
Reason: If you were to consider Newton's third law, it says for every action, there is an equal and opposite reaction. That means if the earth exerts a 440N force on the human, then the human will exert a 440N force on the planet.

Who discovered the surface of venus was noxious and hot?.
The discovery that the surface of Venus is noxious and hot can be attributed to several space missions and scientific observations. However, the first confirmation of Venus's harsh conditions came from the Soviet Venera 4 mission in 1967.
Venera 4, an unmanned spacecraft, successfully descended through Venus's atmosphere and transmitted data back to Earth. The mission's instruments indicated extreme temperatures, atmospheric pressure, and the presence of noxious gases, including sulfuric acid clouds.
This groundbreaking mission provided the initial evidence that Venus has a hostile environment with a thick, toxic atmosphere and intense heat.
Therefore, it was the Soviet Venera 4 mission that played a pivotal role in confirming the noxious and hot nature of Venus's surface.
