Answer:

Conduction of heat

Explanation:

The conduction of heat is defined as the movement of the internal heat energy within the same body due to the crashing and impact of atomic particles and the migration of electrons. This process occurs due to the direct contact of these minute particles.

The heat conduction takes place when any particular object is heated at a high-temperature. Due to this, the particles that are present inside the object acquires energy and starts vibrating. These molecules then flow in the adjacent areas transporting a certain amount of energy.

In the case of metals, the heat conduction takes place very efficiently. So they are considered to be a good conduction of heat.

A sled is pulled at a constant velocity across a horizontal snow surface. If a force of 100 N is being applied to the sled rope

tangare [24]

Answer:

60.18 N

Explanation:

Given that:

The force applied on the sled = 100 N

Suppose, the angle between the sled rope and the ground = 53°

The horizontal force which acts in the horizontal direction can be expressed as:

$F_x = F \ cos \theta$

$F_x = 100 \ cos (53)$

$F_x = 60.18 \ N$

But if the angle between the sled rope is parallel to the ground. Then, we use an angle on a straight line which is = 180°

$F_x = F \ cos \theta$

$F_x = 100 \ cos (180)$

= 100 × -1

= -100 N

An object moves on a trajectory given by Bold r left parenthesis t right parenthesis equals left angle 10 cosine 6 t comma 10 si

spayn [35]

Answer:

Explanation:

(r) = <10 cos 6t, 10 Sin 6t>

The distance traveled by the object is the magnitude of vector r.

The magnitude of vector r is given by

$r = \sqrt{(10 Cos 6t)^{2}+(10 Sin 6t)^{2}}$

$r =10 \sqrt{(Cos^{2} 6t)+(Sin^{2} 6t)$

r = 10
