Answer:
net force acting on the car is zero
Explanation:
given data
mass of car = 1000 kg
slope = 30°
constant speed = 20.0 m/s
to find out
net force acting on the car
solution
we know here that car is moving with given 20 m/s velocity so here net force acting on the car will be zero
as net force is express as
Force = mass × acceleration .....................1
and here acceleration is change of velocity per change in time
and here change in velocity is 0
so that net force will be zero
so net force acting on the car is zero
Final answer:
In this scenario, the car is moving at a constant speed down a slope, which according to Newton's first law of motion, means that the net force acting on the car is zero.
Explanation:
The key to figuring out this problem lies within understanding Newton's first law of motion which states that an object will stay in constant motion as long as the net force acting upon it is zero. In this case, the car is moving at a constant speed implying that the net force, or the sum of all forces acting on it, equals zero. As the car moves down a slope, there's the force of gravity pulling it downwards and the normal force from the road acting upwards. When the car moves in a constant speed, these two forces are balanced, making the net force zero (0 Newtons).

Wood has a high heat capacity.
Wood is an insulator.
Wood is an organic substance.
Answers
Answer: Wood is an insulator.
Explanation: Conductors are those substances which allow heat and electricity to pass through them.Example: Metals
Insulators are those substances which do not allow heat and electricity to pass through them. Example: wood
Pots and pans should be made of conducting material as the heat needs to be transferred from the burner to the pot and then to the food for cooking.
But the handles should be made from insulators so that they do not become hot and thus we can hold the utensil using the handles without getting burnt.
b. the hot and fiery end to the universe
c. the unavailability of energy to do work
d. a theoretical violation of the second law of thermodynamics

Answer: 54 miles in 1hr 30min
Explanation:
The train travels at a constant speed of 36 miles per hour. To find out how far it can travel in 1 hour 30 minutes, we need to convert the time to hours. Since there are 60 minutes in 1 hour, 1 hour 30 minutes is equal to 1.5 hours (1 hour + 30 minutes/60 minutes). To calculate the distance traveled, we multiply the speed of the train (36 miles per hour) by the time it travels (1.5 hours). So, the train can travel 36 miles per hour * 1.5 hours = 54 miles in 1 hour 30 minutes. Therefore, the train can travel a distance of 54 miles in 1 hour 30 minutes
A. -12,000
B. -14,000
C. -16,000
D. -18,000
Answers
Answer:
D. -18,000
Explanation:
Let's define impulse :
- Impulse is defined as the product of Force ( N ) applied on the body and the time of impact ( s ) or
- The change in momentum
hence in this question ,
kara is initially moving with the :
- velocity
= 11
- finally moving with velocity
= -2.5
(minus as she moves in the opposite direction )
therefore the initial momentum =
and the final momentum =
thus the change in momentum : -
= -3250-14300 = -17550 ≅ -18000

Many old structures were made of limestones. Limestone is from Calcium Carbonate (CaCO3) which is an ionic compound and can be used as a building material too.
Final answer:
Ionic solids, such as sodium chloride and nickel oxide, are used as building materials due to their strong bond and high melting points. They are rigid and brittle but can conduct electricity when molten or dissolved.
Explanation:
Ionic solids, such as sodium chloride and nickel oxide, are used as building materials. These solids are composed of positive and negative ions held together by electrostatic attraction. They have high melting points, are rigid and brittle, and do not conduct electricity in their solid state.
However, they conduct electricity when molten or dissolved. Many simple compounds formed by the reaction of a metallic element with a nonmetallic element are ionic. These are crystalline compounds composed of positively charged ions and negatively charged ions held together by electrostatic forces. They have high melting points and are typically brittle.
