Answer:
Please check the explanation.
Explanation:
The slope of the velocity-time graph illustrates the change in velocity with respect to change in time.
In other words, the acceleration of the object is defined by the slope of a velocity graph. The acceleration can be obtained by finding the slope at a particular time.
Hence, the slope of the velocity time graph represent represents acceleration.
2. Also the acceleration of any object, like a car or bike, at some discrete instant in time 't' is termed as instantaneous acceleration which can be determined if we may take the derivate of the given velocity function.
3. A vector that has a direction and magnitude of 1 is termed as a unit vector, often called a direction vector.
The noble gasses, they are the elements on group 18 of the periodic table and do not usually form compounds. The noble gases are as follows: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).
Hope this helped :)
Relation between SI unit and Commercial Unit of energy is 1 kWh = 3.6 × 10^6 J
<u>Explanation</u>:
- Commercial unit of energy is kiloWatt-hour (kWh) and SI unit of energy is Joule (J).
- 1 kiloWatt hour = 1000W × 1h
Now, 1 W = 1 J/sec
⇒ 1 kiloWatt hour = 1000 × 60 × 60 (Since 1 h = 60 × 60 s)
⇒ 1 kWh = 3.6 × 10^6 J
Answer:
246.38N
Explanation:
Check the complete question in the attached diagram
The normal force acting on the body on an inclined is equal to the weight of the object as shown;
Weight = Normal force = mgcosθ
m is the mass of the box = 29kg
g is the acceleration due to gravity = 9.81m/s²
θ is the angle of inclination = 30°
N = 29 * 9.81 * cos 30°
N = 284.49cos30°
N = 246.38N
<em></em>
<em>Hence the magnitude of the normal force is 246.38N</em>
