+ Quả bóng xẹp đương nhiện nhẹ hơn quả bóng được bơm đẩy không khí vì không khí có khối lượng mà. Tuy nhiên sự nặng hơn này rất không đáng kể. Phải có những cân siêu chính xác và độ chia nhỏ mới thấy điều này.

the value of mass of a body is everywhere
Answers
Explanation:
The value of mass of a body is not same everywhere.
Because it depends on gravity and the gravity isn't same at every places.
Answer:
Mass is the quantity of matter contained in a body, while weight is the force by which the body is pulled to the earth's center. Mass is an intrinsic property of a body, as it remains the same everywhere in the universe. Weight is variable due to change in the magnitude of the gravitational force applied by the earth.

what are the newtons law and their formulas
Answers
Answer:
Newton's second law of motion states that the acceleration ( a) experienced by an object is directly proportional to the net force ( Fnet) experienced by the object and inversely proportional to the mass of the object. In equation form, it could be said that a = Fnet/m. The net force is the vector sum of all the individual force values.
Explanation:
Consider the mass-on-a-spring system as shown in the figure below. The spring has a spring constant of 1.81e+3 N/m, and the block has a mass of 0.988 kg. There is a constant force of kinetic friction between the mass and the floor of 1.79 N. Starting with the spring compressed by 0.172 m from its equilibrium position, how far will the block travel once it leaves the spring? (Assume that block leaves the spring at at the spring's equilibrium position, marked x=0 in the figure.
Answers
K1Answer:
s= 6.5cm
Explanation:
Point 1: just right before the block leaves the spring
Point 2: the block has v2=0 (stops moving)
Apply Kinetic-Work Theorem:
K1 + U1 + Wother = K2 + U2
K1=0
U1= 1/2×k×x² (k= 1.81e+3 N/m and x= -0.172 m)
Wother = F×s= 1.79×s
K2=0
U2=0
=> s= 6.5cm
This is my attempt to solve. Let me know if this isn't right

If the toy car weighs 250g and has a kinetic energy of 2.0 J, what is its velocity
Answers
Explanation:
Kinetic energy (J) = 2j
mass= 250g
velocity=?
1kg=1000g
mass= 250/1000
mass=0.25kg
Kinetic energy (J) = ½ x mass (kg) x [velocity]² (m/s)
2=1/2 × 0.25× [velocity]²
2=0.125× [velocity]²
[velocity]² = 2/0.125
[velocity]²=16
velocity= (16)^1/2
velocity= 4 m/s
Hey any physicist or engineer around. am giving brainliest to anyone who will answer this question.
Answers
Answer:
N = 167 Newtons
R = 727 Newtons
Explanation:
i) For static equilibrium, moments about any convenient point must sum to zero.
A moment is the product of a force and a moment arm length. Only the force acting perpendicular to a moment arm passing through the pivot point makes a moment.
ii) I will ASSUME the two moment arms are 0.05m and 0.15 m
CCW moments about the fulcrum are
190 N(0.2 m) + 280 N(0.05 m) = 52 N•m
CW moments are (N)N(0.15 m + 90 N(0.3 m) = 27 + 0.15N N•m
For static equilibrium, these must be equal
27 + 0.15N = 52
0.15N = 25
N = 166.6666666...
Sum moments about N to zero
(Same as saying CW and CCW moments must balance)
190(0.2 + 0.15) + 280(0.05 + 0.15) - R(0.15) - 90(0.3 - 0.15) = 0
R = 726.6666666...
We could verify this by summing vertical forces to zero.
R - 190 - 280 - 166.666666 - 90 = 0
R = 726.6666666...
Denial cycled at 6 mph for 0.8 h. Then he jogged at 2 mph for
1.2 hours. What was Denial's average speed for the total
distance?
mph
Answers
Average speed is difined as the total distance travelled divided by the total time required to cover the distance. Mathematically, it is expressed as:
[tex]Ave. Speed = \frac{Total distance }{Total time}[/tex]
To obtain the average speed of Daniel, we shall determine the distance travelled in each case. This is illustrated below:
Case 1:Speed 1 (S₁) = 6 mph
Time 1 (t₁) = 0.8 h.
Distance 1 (D₁) =?[tex]Speed = \frac{Distance}{Time} \\\\S_{1} = \frac{D_{1}}{t_{1}} \\\\6 = \frac{D_{1}}{0.8}[/tex]
Cross multiply
D₁ = 6 × 0.8
D₁ = 4.8 mileCase 2:Speed 2 (S₂) = 2 mph
Time 2 (t₂) = 1.2 h.
Distance 2 (D₂) =?[tex]S_{2} = \frac{D_{2}}{t_{2}}\\\\2 = \frac{D_{2}}{1.2}[/tex]
Cross multiply
D₂ = 2 × 1.2
D₂ = 2.4 mileNext, we shall determine the total time. This can be obtained as follow:
Time 1 (t₁) = 0.8 h.
Time 2 (t₂) = 1.2 h.
Total time (T) =?T = t₁ + t₂
T = 0.8 + 1.2
T = 2 hNext, we shall determine the total distance. This can be obtained as follow:
Distance 1 (D₁) = 4.8 mile
Distance 2 (D₂) = 2.4 mile
Total distance (D) =?D = D₁ + D₂
D = 4.8 + 2.4
D = 7.2 mileFinally, we shall determine the average speed of Daniel. This can be obtained as follow:
Total time = 2 h
Total distance = 7.2 mile
Average speed =?[tex]Ave. speed = \frac{Total distance }{Total time} \\\\Ave. speed = \frac{7.2 }{2}[/tex]
Average speed = 3.6 mphTherefore, the average speed of Daniel is 3.6 mph
