It does change if the weather is bad then very soon the climate will turn bad when the climate is unfavourable then the sourrounding will be affected. For example if the area around the Mt. Everest is Hot & Humind the ice would start melting & it would lead to way more issues.

The acceleration of the horse's speed which is running at a speed of 35 m/s when it's rider pulls up on the reigns will be -4 m/s².

Acceleration can be defined as the rate of change of velocity with respect to time. Acceleration is a vector quantity as it has both the magnitude and direction. The SI unit of acceleration is m/s² or ms⁻².

The expression for acceleration will be:

a = (v-u)/ t

v = 15m/s,

u = 35m/s,

t = 5 sec,

a = (15-35)/ 5

a = -20/ 5

a = -4 m/s²

Therefore, there will a negative acceleration of 4 meters per second square.

The first one (Work = 160,000 Nm, Power = 160, 000 Nm/sec)

Explanation:

hope this helps :)

A force of 1000 pounds drags a truck 50 feet in 10 seconds. then the work accomplished is 50000 lbs feet and the power required was 5000ft-lbs/sec.

Force is responsible for the motion of an object. it produces acceleration in the body. According to newton's second law force is mass times acceleration i.e. F =ma. Its SI unit is N which is equivalent to kg.m/s². There are two types of forces, balanced force and unbalanced force. Balanced forces are those forces which are opposite in direction and equal in magnitude. When Net force acting on a body is zero then we call it as balanced force. Balanced force is not responsible for the motion of the body. ex. when two persons pulling rope on both end with equal magnitude which cause them to be balanced force have 0 net force. Unbalanced forces are those when resultant of all the forces is not equal to zero is called as unbalanced force. unbalanced force is responsible for the motion of the body.

Given,

F = 1000 pound

s = 50 feet

t = 10 s

Work = F.s = 1000 * 50 = 50000 lbs feet

Power = Work/time = 50000/10 = 5000ft-lbs/sec

Hence option A is correct.

Explanation:

Object A moves with variable speed and Object B moves with constant speed.

Answer: The water Molecules of sample 1 are moving faster

Explanation:

The temperature of the sample in which the color spreads quickly is higher than sample 1. Hence, statement d is correct.

Kinetic energy of a substance is the energy generated by virtue of its motion. It is dependent on the mass and velocity of the substance. Temperature of the system also affects the kinetic energy of substance.

According to kinetic theory of matter, as thermal energy increases, kinetic energy of the particles also increases leading to more effective collisions results in reactions.

Here, the color spreads more easily in sample 2 because the higher temperature of the solution provide enough thermal energy for the liquid particles to gain kinetic energy to easily move through the solution. Thus, statement d is correct.

Force of Friction = -50 (N)

Acceleration = 2.45 (m/s^2)

Explanation:

Force of Friction = f = N * coefficient of friction

N = m * g

=> Force of Friction = m * g * coefficient of friction

f = 20 * 10 * -0.25 = -50 (N)

------------------------------------------------------

(1) F net = F + f

(2) F = m * a

(1) F net = 99 - 50 = 49

(2) a = 49 / 20 = 2.45 (m/s^2)

Answer:

Gravity

Explanation:

Because there this is lot of mass there is a force pulling mass to it, that is gravity.

Explanation:

The cars will slow down as a result of unbalanced forces and negative acceleration.

Inertia is the ability of an object to continue its current motion until and unless some external force causes its speed or direction to change. Inertia is described in the Newton's first law of Motion.

The cars are slowed due to negative acceleration of the object eventually to a stop, because of these unbalanced forces due to friction which are acting on them. The riders, which have inertia, are also acted on by the unbalanced forces throughout the ride causing them to change their state of motion.

Formula and solution:

a = F/m

a = 800 kg.m/s² ÷ 200 kg

Final Answer:

a = 4 m/s²

in the solution there's a two same unit and that is kg so the same unit will be cancelled and the rest is going to aapply in the answer that is 4 so if combine it the final answer is 4 m/s²
