Chanel has some cotton candy that came in a cloudy shape. She wants to make it more dense. Which describes the candy before and after Chanel manipulated it?

Answers

Answer 1

Answer: The candy before has undergone physical change after manipulation because it says that it will make the cotton candy denser. Making it denser probably doesn't have to change any chemical components of the candy.

The Hubble telescope’s orbit is 5.6 × 105 meters above Earth’s surface. The telescope has a mass of 1.1 × 104 kilograms. Earth exerts a gravitational force of 9.1 × 104 newtons on the telescope. The magnitude of Earth’s gravitational field strength at this location is

Answers

Gravitational force = 9.1 x 10⁴ newtons

Mass = 1.1 x 10⁴ kilograms

Gravitational field strength = 9.1 x 10⁴ newtons / 1.1 x 10⁴ kilograms

= ( 9.1 / 1.1) (newton / kilogram)

= 8.3 newton/kg

or 8.3 m/s² .

Typically, water runs through the baseboard copper tubing and, therefore, fresh hot water is constantly running through the piping. However, consider a pipe where water was allowed to sit in the pipe. The hot water cools as it sits in the pipe. What is the temprature change, (ΔT), of the water if 193.0 g of water sat in the copper pipe from part A, releasing 2665 J of energy to the pipe? The specific heat of water is 4.184 (J/g)⋅∘C.

Answers

Answer: The temperature of the water falls by 3.3°C

Explanation:

The heat change is related to the change in temperature by the equation

dH = m Cp dT

In this example, -2665 J = 193 g x 4.184 J/g°C x dT

so dT = -3.3 °C

What is cosmic background radiation?

Answers

Cosmic background radiation is the energy left over from the big bang and it's everywhere we look so if we consider ourselves the center, no matter which way we look we see this cosmic background radiation which is left over energy from the big bang.

Cosmic background radiation is electromagnetic radiation from the sky with no discernible source. The origin of this radiation depends on the region of the spectrum that is observed.

In a closed system, glider A with a mass of 0.40 kg and a speed of 2.00 m/s collides with glider B at rest with a mass of 1.20 kg. The two interlock and move off. What speed are they moving at?

Answers

The speed are they moving at will be 0.5 m/sec.Law of conservation of momentum is applied.

What is the law of conservation of momentum?

According to the law of conservation of momentum, the momentum of the body before the collision is always equal to the momentum of the body after the collision.

The given data in the problem is;

(m₁) is the mass of 1st gilder= 0.40 kg

(u₁) is the initial velocity = 2 m/s

(m₂) is the mass of 2nd gilder = 1.20 kg

(u₂) is the initial velocity of 2nd gilder = 0 m/s

(v) is the velocity after collision =.?

According to the law of conservation of momentum;

Momentum before collision =Momentum after collision

$\rm m_1u_1 + m_2u_2 = v(m_1 + m_2)\n\n(0.40* 0.25) + (1.2 * 0) = v * (0.40+1.20) \n\n 125 + 0 = v * (1250) * 125 \n\n \rm v= (0.8)/(1.6) \n\n \rm v= 0.5 \ m/sec$

Hence, the speed are they moving at will be 0.5 m/sec

Conservation of momentum.
m1*u1 + m2*u2 =m1*v1 + m2*v2
here u2=0 body at rest, v1=v2=v both interlock and move together
0..4*2+1.2*0 = 0.4*v+1.2*v
v= 0.8/1.6 = 0.5 m/sec
