if a 60 kg person was standing on a platform at the surface of saturn and they jumped, they would have to push with a force greater than..?

Answer:

t

Explanation:

Answer:

False

Explanation:

Answer:

A) The initial velocity is 11.27 m/s

B) The maximum velocity is 11.27 m/s

Explanation:

A) The question is with regards to kinematic motion under gravity

The the time it takes the ball to travel up and return back to the ground = 2.30 seconds

Therefore, from the kinematic equation of motion of the ball, under gravity, v = u - g·t, we have;

t = (v - u)/g

Where;

t = The total time of the motion of the ball = 2.30 seconds

v = The final velocity of the ball = 0 m/as at the maximum height

u = The initial velocity of the ball

g = The acceleration due to gravity = 9.8 m/s²

Therefore, given that we have;

The time it takes the ball to ascend = The time it takes the ball to descend

The time it takes the ball to ascend to maximum height = 2.30 second/2 = 1.15 seconds

Substituting the parameter values of the motion to maximum height, we get;

1.15 = (0 - u)/(-9.8)

-9.8 × 1.15 = -u

11.27 = u

The initial velocity, u = 11.27 m/s

B) Given that the ball experiences a deceleration on the way up, and that the motion of a parabola is symmetrical about the vertex, which is the maximum height, where the velocity is zero, we have that the initial velocity is equal to the final velocity which are both equal to the maximum velocity

Therefore, the initial velocity = The maximum velocity = 11.27 m/s.

Explanation:8=3×1019 electrons per second.

Answer:

3000W

Explanation:

Given parameter:

Weight of safe  = 2000N

Height of lift = 6m

Time = 4s

Unknown:

Power used by Rudolph = ?

Solution:

Power is the rate at which work is being done. It is expressed as:

 Power  = [tex]\frac{Work done }{Time taken}[/tex]  

   Work done  = Weight x height = 2000 x 6  = 12000J

Power  = [tex]\frac{12000}{4}[/tex]   = 3000W

By placing it in water and measuring how high the water rises

Explanation:

You can place the object in a can filled with water. You'll then see that as it sits there, the water level rises. You would then measure that to find the volume.

Answer:

The equivalent resistance of the parallel circuit would be 20 Ω

Explanation:

To calculate the resistance of resistors connected in parallel, the formula to be used is

1/R = 1/R₁ + R₂ + R₃ + R₄...

1/R = 1/120 + 1/60 + 1/40

1/R = (1 + 2 + 3)/120

1/R = 6/120

1/R = 1/20 Ω

This can be rewritten or cross-multiplied to be

R × 1 = 20 × 1

R = 20 Ω

The equivalent resistance (R) would then be 20 Ω

Answer:

14.7 J

Explanation:

PE=MGH

PE= 1.0 x 9.8 x 1.5 = 14.7 J

Answer:

k. e. = 1/2 mv^2

1/2 * 1000 * (5)^2

1/2 * 1000 * 25

12500 joules

k. e. = 1/2 mv^2

1/2 * 1000 * (10)^2

1/2 * 1000 * 100

50000

change in k. e. = final - initial

50000 - 12500

= 37500 joules

The normal force felt by the box has magnitude

F[normal] = (1 kg) g = 9.8 N

so that the maximum magnitude of static friction is

F[s. friction] = 0.8 F[normal] = 7.84 N

In order to get the box to move, (C) a minimum force of 7.84 N is required.

Answer:

Explanation:

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

[tex]a = \frac{f}{m} \\ [/tex]

f is the force

m is the mass

From the question we have

[tex]a = \frac{0.8}{1.2} \\ = 0.666666...[/tex]

We have the final answer as

Hope this helps you

Answer:

In order to convert density to grams, you have to put the mass on one side of the equation, and the density and the volume on the other. Therefore, d * v = m. Multiply the density by the volume. Using the example in step 1, you would multiply 2 g/mL by 4mL.

Answer:

Answer:

Explained below.

Explanation:

The ball doesn't fall behind the moving cart because the horizontal motion of the ballistic cart is not affected by the forces that act in the vertical direction. Therefore, when the cart is pushed, it means that the ball will shoot up and then it will land right back in the barrel.

Answer:

I bet my great grandmother would

Answer:

Explanation:

b )

Normal force R = mgcosθ

= 76.6 x 9.8 x cos 38

R = 591.5 N

c )

Force of friction

= μ R

μ is coefficient of friction .

= .15 x 591.5

= 88.73 N

d )

Net force

= mg sinθ - friction

= 76.6 x 9.8 x sin 38 - 88.73

= 462.16 - 88.73

= 373.43 N

Acceleration = 373.43 / 76.6

a = 4.87 m / s²

e )

v² = u² + 2 a s

s = 40.5 m

a = 4.87

u = 0

v² = 0 +2 x 4.87 x 40.5

= 394.5

v = 19.86 m /s

f )

v = u + a t

19.86 = 0 + 4.87 t

t = 4 .07 s

heyyy

May I Know the full question

Answer:

Nothin will move, it will stay the same since no force is greater than the other. it's "the same amount of force" which also means an equal amount of force

Explanation:

The forces are only equal if there is no acceleration (which in the game of tug of war, accelerating yourself and your opponent is the idea). If the force on the rope and the ground are both equal either nothing moves or some other force is being applied in the system.

Answer:

Answer:

A. 2.2 ɥC

Explanation:

Given;

electric field strength, E = 1236 N/C

distance of the source charge, r = 4 m

Electric field strength is calculated as;

[tex]E = \frac{kQ}{r^2}[/tex]

where;

Q is the magnitude of the source charge

k is Coulomb's constant = 9 x 10⁹ Nm²/C²

[tex]E = \frac{kQ}{r^2} \\\\kQ = Er^2\\\\Q = \frac{Er^2}{k} \\\\Q = \frac{(1236)(4^2)}{9 \ \times \ 10^9} \\\\Q = 2.197 \ \times \ 10^{-6} \ C\\\\Q = 2.197 \ \mu \ C[/tex]

Therefore, the correct option is A. 2.2 ɥC

Answer:

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.
